Application of in situ stress regression method in rock slope stability analysis

Abstract

A detailed study about the application of in situ stress field in engineering slope has been carried out. To take the in situ stress into account in analysis of slope stability, the parent-model with coarse grids and sub-model with fine grids was established. In order to determine the in situ stress field of slope, the regional stress field calculated by stress regression method was converted to stress boundary of sub-model. The analysis of slope stability based on the in situ stress field is accurately to reflect the effect of natural factors. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
