The pressuremeter is a versatile piece of ground investigation equipment that can be used to test any type of soil or rock in situ. It quantifies in-situ stress, stiffness, strength and permeability – the essential properties needed to design geotechnical structures. The results are used in pressuremeter specific design methods, empirical design methods and numerical analyses.

This reference book covers the types of pressuremeter and the control equipment, methods of installation, test procedures, methods of analysis including direct and indirect methods of interpretation, and application in design. This is supported by an exemplar specification for field operations with the interpretation of the results. Engineers are given enough detail to apply the results confidently.

This comprehensive and thorough discussion of pressuremeter testing in geotechnical design draws on over forty years’ experience in geotechnical engineering. It is essential for professional and academic engineering geologists and geotechnical, civil and structural engineers involved in ground investigation and geotechnical design.

Jean-Louis Briaud ... 1024 pages - Publisher: Wiley; (October, 2013) ... Language: English - ISBN-10: 0470948566 - ISBN-13: 978-0470948569.

The first introductory geotechnical engineering textbook to cover both saturated and unsaturated soil mechanics: Most books designed for an introductory course in geotechnical engineering focus on saturated soil mechanics. Geotechnical Engineering: Unsaturated and Saturated Soils takes a new approach, based on the fundamentals of unsaturated soils and extends the description to a wide variety of applications.

Written by an international leader in the field, this comprehensive introduction presents geotechnical engineering as dealing with a true three-phase soil while treating saturated soil as a special case, rather than the other way around. It covers numerous topics that reveal the vast domain covered by geotechnical engineering and its important contributions to many elements of infrastructure. It includes, in addition to conventional subjects, a number of topics typically left out of undergraduate geotechnical courses, such as: Engineering geology + Rocks + Site investigation and in situ tests + Geophysics + Problem solving methods and soil models + Thermodynamics for soils + Earthquake geo-engineering + Erosion + Geoenvironmental + Geosynthetics + Ground improvement+ Technical communications. Geotechnical Engineering: Unsaturated and Saturated Soils takes students beyond the usual confines of an undergraduate introduction to become a useful reference as they enter graduate studies or begin their careers.

PLAXIS 2D CONNECT Edition V22 Update 1 [Size: 2.4 GB] ... PLAXIS 2D is a powerful and user friendly finite element package intended for two-dimensional analysis of deformation and stability in geotechnical engineering and rock mechanics. PLAXIS is used worldwide by top engineering companies and institutions in the civil and geotechnical engineering industry. Applications range from excavations, embankment and foundations to tunnelling, mining and reservoir geomechanics.

PLAXIS is equipped with a broad range of advanced features to model a diverse range of geotechnical problems, all from within a single integrated software package. PLAXIS uses predefined structural elements and loading types in a CAD-like environment. This empowers the user with fast and efficient model creation, allowing more time to interpret the results.

Since PLAXIS V22 Update 1 also contains the new data structure of the material database and the more flexible and more robust way of handling project units introduced in the previous release, similar precautions apply with respect to V21 release compatibility. PLAXIS V22 Update 1 will be installed alongside PLAXIS V21, instead of overwriting it. Calculated V21 projects opened with this latest release will automatically be saved as a converted copy with the _converted suffix. After the conversion, remeshing and recalculation are required. In this case, the original V21 project will remain unchanged. For V21 projects that only have their geometry and/or some material sets defined and may be either meshed or not, these projects will be opened by V22 Update 1 without converting to a saved copy. The original V21 project would be overwritten upon saving.

The known issue that caused the assignment of the material factor labels to the material models parameters to be lost, when a V21 project containing Design Approaches is opened with V22 is now fixed in the latest release. Note that these converted projects are stored in the file format for PLAXIS V22 Update 1, this means that earlier versions of PLAXIS will not be able to open the converted project files. To continue using V21, users can just open the original V21 project.

Tunnels have a high degree of risk that needs to be assessed and managed. Underground works intersect and interact with natural materials, incorporating their characteristics as structural components of their own stability. For this reason geotechnical risk analyses are implemented at all phases of tunnel construction, from design through to post-construction maintenance. Analysis of geotechnical risk involves a group of studies which lead to the identification and evaluation of the potential probability of error and the consequences of its occurrence. This volume considers construction and safety, financing and control, and exploration and maintenance. Eminent specialists discuss risk assessment and management, based both on advanced theoretical concepts and on practical experience. The book is of interest to a wide range of professionals involved in planning, construction and management of tunnels: entrepreneurs, designers, consultants and contractors.

Modeling and computing is becoming an essential part of the analysis and design of an engineered system. This is also true of "geotechnical systems", such as soil foundations, earth dams and other soil-structure systems. The general goal of modeling and computing is to predict and understand the behaviour of the system subjected to a variety of possible conditions/scenarios (with respect to both external stimuli and system parameters), which provides the basis for a rational design of the system. The essence of this is to predict the response of the system to a set of external forces. The modelling and computing essentially involve the following three phases: (a) Idealization of the actual physical problem, (b) Formulation of a mathematical model represented by a set of equations governing the response of the system, and (c) Solution of the governing equations (often requiring numerical methods) and graphical representation of the numerical results. This book will introduce these phases.

The presence of thick deposits of soft clay combined with the effects of ground subsidence cause problems for engineering constructions for lowland areas such as the Central Plain (Chao Phraya) of Thailand. The ground subsidence is caused by the excessive extraction of ground water. To mitigate such natural geological hazards, different soil/ground improvement methods have been studied, namely: mechanically stabilized earth (MSE) embankments, granular or sand compaction piles, vertical drains, and the lime/cement deep mixing method. In view of their proven performance, durability, constructibility, short time schedule, and low costs, mechanically stabilized earth (MSE) or earth reinforcement techniques seem to be very suitable and favorable above-ground soil improvement methods of embankment fills on subsiding ground. This method can be most appropriately combined with the various belowground improvement techniques such as vertical drains, sand compaction piles, and the lime/cement deep mixing method. Thus, the combined above-ground soil improvement with below-ground subsoil improvement schemes can be a viable alternative to the existing method of supporting earth embankments and landfills with precast concrete piles, which may prove detrimental and more expensive in a subsiding environment.
