Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwate...

The products of the Information Age give geotechnical engineers powerful tools to perform their work. One view of geotechnical engineering is that Information Technology (IT) tools may replace many of the functions that geotechnical engineers now perform. This view can be framed to argue that the right IT tools will even replace the need for engineering judgment. Since geotechnical engineers re...

Geotechnical instruments are used widely as a complementary tool to geodetic methods in monitoring natural and man-made structures. This paper provides an overview of geotechnical instruments used in structural monitoring. The transducers commonly used in geotechnical instrumentation are first introduced. This is followed by an introduction of the various types of instruments including their wo...

Geology and the detailed understanding of its properties are fundamental to the optimal design and successful operation of any mine. To that end, extensive fieldwork was conducted at Sandsloot open pit (PPRust— Anglo Platinum) to collect geotechnical information both from exploration boreholes and in-pit mining faces. Over a fie-year period, geotechnical data were collected from 29, 213 m of ex...

We present an information architecture using Web services for exchanging and utilizing geotechnical information, which is of critical interest to a large number of municipal, state and federal agencies as well as private enterprises involved with civil infrastructures. For example, in the case of soil liquefaction hazard assessment, insurance companies rely on the availability of geotechnical d...

Abstract—Multi criteria decision analysis (MDCA) covers both data and experience. It is very common to solve the problems with many parameters and uncertainties. GIS supported solutions improve and speed up the decision process. Weighted grading as a MDCA method is employed for solving the geotechnical problems. In this study, geotechnical parameters namely soil type; SPT (N) blow number, shear...

The occurrence of hazard events in geotechnical practice is often associated with geotechnical uncertainties. To prevent hazard events from happening or reduce the impacts of their consequence, sources of geotechnical uncertainties need to be identified and treated, and appropriate control measure has to be implemented throughout a project. The probabilistic methods are the devices dealing with...
