Based On The Deformation Theory Of Slope Stability Analysis

Slope stability analysis is the core of slope engineering research. The complex geological conditions for the terrain slope, in order to accurately determine the slope stability is a major engineering challenge. With the construction of the rapid development of large-scale hydropower projects and lines engineering will inevitably produce damage to the terrain slope, affecting the slope stability, and some even produce landslides. Slope stability studies to examine how to deal with landslide reinforcement has important practical significance of the project.A certain reservoir dam spillway slope stability and affect the normal operation of the reservoir storage key projects. Slope excavation, the slope varying degrees in different parts of the deformation. In this paper, the practical engineering problems in complex geological conditions slope of a full on-site investigation, and had get the following conclusions:1. A comprehensive analysis of engineering geological conditions of slope, rock structure and deformation characteristics of geological conditions from the slope of the deformation mode of starting to study the deformation and failure.2. Established the geological conceptual model of the spillway slope, FLAC finite difference method was used two-dimensional analysis of the natural state of the slope obtained stress field.3. After analysed of the state to determine the slope, the slope after excavation to grade stress and deformation characteristics of slope simulation, numerical simulation obtained from the sign of slope deformation and failure modes, from the calculated results, can occur with the slope of the actual situation in different parts coincide.Through this research, the reservoir spillway slope stability can not meet the normal operation, need to be further processed to meet the engineering application.
