Analysis and application of deep deformation and failure modes for slopes in Paleogene red-bed area of the Yellow River to Xining Diversion Project
摘要
Abstract
In order to establish typical deep deformation and failure modes for slopes in the Paleogene red-bed area of the Yellow River to Xining Diversion Project,and to identify deep failure-type slope deformation masses,based on investigation and analysis results of slope deformation and failure phenomena in the water supply area,the formation mechanism of each discovered deep-failure red-bed landslide mass was analyzed,and a reverse analysis was conducted to determine the geomechanical characteristics of natural slopes before the formation of red-bed landslides.Numerical simulations were performed to analyze the key factors causing deep deformation failure of natural slopes in the Paleogene red-bed area,and typical deep deformation and failure modes for slopes in the Paleogene red-bed area were established.Slope deformation masses with the geological structural characteristics of typical deep deformation and failure modes were identified in the Paleogene red-bed area,and a three-dimensional numerical simulation model was established to analyze the deformation and stability characteristics of these deforming slope under natural,seismic,and rainfall conditions,and identify deep failure-type slope deformation masses.The results show that the deep deformation and failure mode for slopes in the Paleogene red-bed area is related to the stratum rock segments.According to the established typical deep deformation and failure mode for slopes,a potential deformation mass is identified along the No.24 branch line of the water supply project in the Paleogene red-bed area,showing poor stability under rainstorm conditions.关键词
