Geotechnical Instrumentation and Applications explains the geotechnical issues encountered in the implementation of construction projects dealing with ground, groundwater, and earth infrastructures, including land reclamations, dams, embankments, landfill construction, excavations, and tunnelling. The book describes the types of geotechnical instrumentation available in the market and walks readers through the geotechnical issues usually encountered in construction projects and observational methods applying geotechnical instruments, planning, and implementation of geotechnical instrumentation projects. Detailed coverage of the calibration and installation process of geotechnical instruments, the verification of measured data, and the recording and documentation of as-built drawings of geotechnical instruments installed are presented. Coverage also includes methods of measurement, recommended monitoring frequencies for manual monitoring and methods of data processing and presentation, as well as analyses and interpretations of monitored data for performance assessment. Factors affecting measured instrument data are also discussed with a few examples. Case studies are presented with field data collected during the implementation of large-scale ground improvements and ground engineering projects involving extensive geotechnical instrumentation works. The book will be an ideal text for upper-undergraduate and graduate geotechnical engineering, foundation engineering, and soil mechanics courses and a hands-on reference for practitioners who apply geotechnical instrumentation in the construction industry.

Geotechnical investigation, which is usually implemented to obtain baseline information of ground and groundwater, is the focus of this book. Authored by practitioner and academic who is extensively involved in geotechnical ground investigations over four continents, this book covers both large scale preliminary ground investigation and intrusive detailed investigation, as well as specialized in-situ testing to obtain advanced geotechnical parameters of soils. Both surface and borehole geophysical methods used in geotechnical investigation, including methods of sampling and tools to obtain good quality soil samples are also discussed and presented in the book. Written for advanced undergraduate and graduate students, researchers and practitioners in the fields of geotechnical engineering, geoenvironmental engineering, and ground investigation, the book also provides guidelines on presenting factual geotechnical data and preparing factual reports.

The formation of an alluvial clay deposit normally goes through sedimentation and consolidation. While the bottom portion is undergoing self-weight consolidation, sedimentation continues to take place at the top. However, the compression behavior of such deposits upon loading is not well understood. This book describes the compression behavior of ultra-soft soil upon additional load application. Various types of laboratory compression tests suitable for this type of soil are discussed, such as tests using small- and large-scale consolidometers, hydraulic Rowe cells under different drainage conditions, constant rate of loading and constant rate of strain tests. It also explains how to determine the transition point, which differentiates the two distinct behaviors between slurry state and soil state deformation. Methods to determine the compression indices and coefficients of consolidation at different stress ranges, which are required for the prediction of magnitude of settlement and time rate of settlement, are developed. An equation for predicting settlement of ultra-soft soil in both the slurry and soil stages is elaborated upon. These proposed methods of characterization or analyses — which are validated against published data, laboratory measurements and a case study — serve as useful tools for designing and constructing embankments and for carrying out land reclamation on ultra-soft soil.
