Slope stability is one of the most complex and essential issues for civil and geotechnical engineers, mainly due to life and high economical losses resulting from these failures. In this paper, a new approach is presented for estimating the Safety Factor (SF) for circular failure slope using hybrid support vector regression (SVR) and Ant Colony Optimization (ACO). The ACO is combined with the S...

The simulation of structural and geotechnical systems is a critical step in their design and assessment. The purpose of an earthquake simulation is to estimate the performance of the system under seismic excitation or loads that represent the effects of an earthquake. Structural and geotechnical simulation has a long history of development in earthquake engineering. The computation required to ...

Official Seismic Hazard Zone Maps of Dublin, Livermore, and Altamont 7.5-minute quadrangles (1:24,000 scale) show areas that may be susceptible to earthquake-induced liquefaction. The maps are the result of the three-dimensional integration of geotechnical and geological data. Approximately 450 geotechnical borehole logs were collected, analyzed, entered into a geotechnical Geographic Informati...

Modern ground-water flow models, geotechnical studies, and science-based land-use planning require knowledge of the distribution of surficial earth materials from land surface to the top of bedrock (e.g., Masterson and others, 1997a,). To be useful, modern geologic maps must portray such information three dimensionally in a way that is consistent with the regional stratigraphic framework, geote...

The void index is a relative quantity measuring the position of the current void ratio of a clay against the void ratios of the clay at two specific vertical effective stresses (i.e., σ v ′ = 100 kPa and σ v ′ =1000 kPa). Based on this concept, a simple systematic tool is proposed for estimating the compression behaviour of reconstituted clays over a wide range of stresses and water contents. F...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration; Project Title: Implementation of Research Results Regarding Shear Strength and Stability of Embankments 16. Abstract A number of TxDOT-sponsored studies and research projects have been conducted over the years regarding shear strength and slope stability i...

A desktop Geographic Information Systems (GIS) for Geotechnical Information Management system has recently been developed to assist geo-technical managers, planners through flexible application with all common desktop GIS functionalities and customized tools like Borehole Viewer and Stripchart to relate alignments and cross-sections to a specific location and/or region on the map, and create th...
