Soft Clay Engineering and Ground Improvement covers the design and implementation of ground improvement techniques as applicable to soft clays. This particular subject poses major geotechnical challenges in civil engineering. Not only civil engineers, but planners, architects, consultants and contractors are now aware what soft soils are and the risks associated with development of such areas. The book is designed as a reference and useful tool for those in the industry, both to consultants and contractors. It also benefits researchers and academics working on ground improvement of soft soils, and serves as an excellent overview for postgraduates. University lecturers are beginning to incorporate more ground improvement topics into their curricula, and this text would be ideal for short courses for practicing engineers. It includes several examples to assist a newcomer to carry out preliminary designs. The three authors, each with dozens of years of experience, have witnessed and participated in the rapid evolvement of ground improvement in soft soils. In addition, top-tier professionals who deal with soft clays and ground improvement on a daily basis have contributed, providing their expertise in dealing with real-world problems and practical solutions.

The cone penetration test (CPT) has been widely used in Louisiana in the last two decades as an in situ tool to characterize engineering properties of soils. In addition, conventional drilling and sample retrieval using Shelby tube followed by laboratory testing is still the acceptable practice in identifying soils engineering properties. The main objective of this project is to update the correlations that are currently used by Louisiana Department of Transportation and Development (LADOTD) to interpret CPT data for engineering design purposes and to assess the reliability of using CPT data to predict soil shear strength in both the magnitude and spatial variations in the field with respect to the Load and Resistance Factor Design (LRFD) methodology. The results of laboratory soil testing were retrieved from borehole logs and were used as reference measurements in this study. The research team collected project data files in paper printout format from LADOTD and soil testing engineers. Most project files did not have spatial coordinates; therefore, aerial images were used to identify latitude and longitude coordinates of CPT and borehole locations. The borehole data was not available for all the located CPT soundings. Efforts were made to obtain any available data from LADOTD electronic archive as well as paper project documents. A total of 752 CPT tests were documented in which 503 were matched with adjacent boreholes and 249 did not have adjacent borehole data available. The CPT data was used to predict soil undrained shear strength, bulk density and classification according to Robertson and Zhang and Tumay methods [1], [2]. The CPT data was then used to develop a database of undrained shear strength estimates with corresponding results from boreholes. The results in the database were preprocessed to apply some constraints on data points included in the calibration study, such as setting a maximum threshold on the distance between CPT and borehole locations; a minimum and maximum threshold on undrained shear strength values were used to represent realistic soil properties. The resulting database included results from 251 CPT soundings with borehole results in their vicinity that meet the aforementioned constraints. From these CPT soundings, 862 unique undrained shear strength data points were obtained at various depths. The dataset was analyzed for general as well as specific trends in order to identify appropriate parameters to be included in the study. Soil classification was clearly the most plausible parameter based on which the CPT undrained shear strength estimates should be calibrated. The calibration of the CPT expression for undrained shear strength was conducted using two approaches. The first approach is a direct correlation based of the transformation model currently used by LADOTD for estimating the shear strength. The First Order Reliability Method (FORM) forms the basis for the second approach, which is more detailed and accounts for all sources of uncertainty. Optimum CPT coefficient values were computed for various target reliability values. The results were summarized and implementation procedures were recommended for future research.

The Engineering of Foundations presents the subject of foundation engineering in a logical framework, in a natural sequence and in as simple a presentation as possible. The text emphasizes conceptual understanding and avoids and an oversimplistic treatment of the subject. Estimation of soil parameters for use in design is given high priority. Users will find an up-to-date text that relates theory to real world practices and integrates concepts and continuity of examples across chapters. Illustrations, applications and hands-on examples are provided, to explain these critical foundations. Explains the "why". One reviewer notes, "This is the Holtz and Kovacs of Foundations!!"

Fourteen papers from the 1999 conference consider soils derived in place as a result of long-term weathering processes of the underlying bedrock formations, which creates a layer of varying stages of decomposed rock nature between the soil and the totally unweathered bedrock. They describe several methods of characterizing the three layers, both in the field and in the laboratory, and suggest measures engineers can take to stabilize them before building on them. Four case studies are included.

"Soils and rocks are complex natural geomaterials that exhibit a wide range in strength, stiffness, state of stress, structure, and flow characteristics. Geotechnical & Geophysical Site Characterization provides eleven keynote state-of-the-art papers, including the Mitchell Lecture. A total selection of 219 technical papers and theme reports address methods of site exploration related to ground exploration for civil engineering and construction works. These two volumes represent a collection of experience & knowledge regarding various methods of in-situ testing, geophysical techniques, innovative devices, improved interpretation algorithms, and statistical treatment of field data for the characterization of soils, rocks, and other geomaterials. The papers represent the written records and documented efforts from international experts from industry, academe, and government who participated in the Second International Conference on Site Characterization held in Porto, Portugal on September 20-22, 2004. Topics include the utilization of rotary drilling, sampling, and coring techniques. Of particular interest is the variety of in-situ tests, including standard penetration, cone penetration, flat dilatometer, pressuremeter, vane shear, piezocone, dynamic probes, and specialized tools, as well as geophysical approaches: resistivity surveys, surface waves, crosshole, downhole, electromagnetic conductivity, and ground penetrating radar. A careful and proper site evaluation is required in the analysis and design of new structures, construction monitoring, and forensic studies that require remediation. Many of the contributions relate to case studies of projects that involve shallow foundations, drilled shafts, pilings, slope stability, excavations, earth dams, tunnels, and mining. Several papers discuss a combined approach using multiple methods and/or complementary set of geotechnical & geophysical tests to ascertain the characteristics of the ground."--back cover.

"Caltrans' investment in driven piling to support bridges and other structures has averaged about $25M/year over the last decade. The systems constructed have performed well, but conservatism exists due to uncertainties in soil properties, pile drivability, soil-pile interaction, and pile setup. A new method that could achieve modest saving of 5% in design could save in excess of $1M per annum. This report presents the development of a reusable instrumented test pile (RTP) as an in situ testing device for improved pile design in granular soils (coarser than No. 200 sieve). The RTP system consists of short instrumented sections that provide measurements of axial load, radial stress, pore pressure, and acceleration, and are connected in series with standard Becker pipe sections. The RTP - Becker pipe string is driven using the standard Becker pile driving hammer, and the TRP system was designed to handle the high installation stresses in granular soils while retaining sufficient resolution in the instrumentation readings for subsequent analyses of shaft and tip resistances. RTP measurements obtained during driving provide detailed information regarding pile drivability, measurements during static tests capture load transfer along the pile, and measurements during pile setup capture capacity gain over time. The design, fabrication, calibration, proof testing, and full scale field deployment are presented herein."--Technical report documentation p.
