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...

Over the last few years or so, the use of artificial neural networks (ANNs) has increased in many areas of engineering. In particular, ANNs have been applied to many geotechnical engineering problems such as to predict pile capacity, settlement, liquefaction etc. The correlations between shear strength parameters and other soil properties individually are common among Geotechnical engineers. Bu...

due to its critical impact and significant destructive nature during and after seismic events, soil liquefaction and liquefactioninduced lateral ground spreading have been increasingly important topics in the geotechnical earthquake engineering field during the past four decades. the aim of this research is to develop an empirical model for the assessment of liquefaction-induced lateral ground ...

breakwaters are the important and the costly ones of the marine structures. composite breakwater is one of the common types in the world. because of the sensitivity of composite breakwaters to environmental conditions, also construction costs, difficulty of repair and maintenance and importance of equipments on and behind the breakwater, design of composite breakwater must be very accurate. goa...

The displacement back analysis is an effective means on inversion of rock mechanical parameters. Differential evolution algorithm has many advantages and good prospects to solve problems of geotechnical parameters. The program is used to the simulation of the true tunnel with C++ language, while it is embedded into differential evolution algorithm to achieve the inversion parameter. Applying to...

The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures. Since swell potential and swell pressure are key properties of expansive soils, the swell parameter...

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...

This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...
