Geotechnical engineering is a relatively new discipline that has developed rapidly over the past 30 years. It deals with a wide spectrum of natural geological materials ranging from low strength soils to high strength rocks. Earth movements are common in many parts of the world and, as a result, present serious safety and mortality risk to humans in addition to affecting construction activities...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

Geotechnical engineering deals with the safe transmittal of loads due to various engineering applications to, and into, the soil or rock mass. The soil and rock mass formations are heterogeneous and generally are subjected to stresses (due to various engineering applications) which are additional to those presently existing in the earth mass from its self weight and geological history. Due to t...

Blast-induced seismic wave is very important to theory study of structure damage and stability analysis of corresponding geotechnical engineering; however it is not well solved. Based on measured data of Lafarge quarry, shortcoming of traditional analysis method is pointed out. Wavelet analysis method is presented to describe spectral characteristics and energy distribution of blast-induced sei...

This paper considers the uncertainties in geotechnical parameters of earth fill structures, s pecifically their spatial variability. The use of random field theory will be introduced, in conjunction with the stochastic finite element method, to describe and m odel the uncertainty in geotechnical properties of compacted soil masses. The paper focuses on the imp ortance of the use of conditional ...

Geological engineers have mostly been involved in geotechnical problems since the beginning of 19 century. Engineering geological maps and field data are needed to solve these problems. The amount of data for these maps is extremely large, so putting all the map elements on the map sheet causes difficulties while solving problems. The magic words, Geographic Information System (GIS) is a tool f...

The first stage of any major civil engineering project generally involves some form of preliminary reconnaissance study of project sites followed by detailed geotechnical investigation. Primary aim of this study is to collect data concerning physical characteristics of terrain and ground conditions in order to assess their likely influence on the overall design and performance of infrastructure...
