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...

Surveillance of large geotechnical projects requires autonomous collection of data from a wide range of instrument types. An equally large range of data formats are employed by these measurement systems. A data exchange protocol is needed to make field data available for interpretation on a variety of platforms. This paper presents the results of the development of a robust Internet-enabled fra...

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...

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...

In order to mitigate hazards of mass failure, the first step is the identification of potentially unstable slopes, resulting in a landslide susceptibility map. Satellite imagery is an important component in the derivation of critical parameters. Susceptibility maps can be constructed in a variety of ways, including multivariate statistics, heuristic models, and geotechnical models. Each method ...

In this research, a new method is proposed to update system reliability based on data recorded by instruments and sensors installed on geotechnical systems to reduce uncertainties. The method is founded on Bayesian analysis and Monte Carlo simulation and is capable of estimating the functional relationship between the updated failure probability and the monitoring value. It is shown that as lon...

This research paper presents a compendium of the geotechnical sub-soil data profiling and zoning of the major urban settlements of Peshawar using Geographic Information System. Significant geotechnical properties of the under study area soils i.e., Zone 5 & 6 in Peshawar were assessed through one hundred and three different standard penetration test reports up to the depth of 1 m and 3 m. The q...

Benford’s law predicts the frequency of the first digit of numbers met in a wide range of naturally occurring phenomena. In data sets, following Benford’s law, numbers are started with a small leading digit more often than those with a large leading digit. This law can be used as a tool for detecting fraud and abnormally in the number sets and any fabricated number sets. This can be used as an ...

Rover-mounted geotechnical systems are of paramount importance to lunar trafficability assessment, construction, and excavation/mining toward establishing permanent human presence on the Moon. These tools can also be used to determine density, when the regolith is used as radiation shield, for example. Two popular insitu devices for establishing geotechnical properties of soil are the Static Co...
