摘要
顺层滑坡往往对工程建设造成严重的灾害,根据某坡体的地质背景和工程地质特征,建立了顺层滑坡的地质模型,对某段高速公路的路堑边坡从开挖至治理阶段,用数值模拟进行了较全面的分析,模拟了顺层滑移坡体不同开挖阶段的稳定性和工程处理方案。根据实践检验,分析结果与现场情况基本一致,证明这种数值模拟分析方法具有一定的可信性和优越性,其研究成果对类似工程具有指导意义。
Bedding-landslide usually a threat to engineexing the construct of project, according to the geologic background and the engineering geologic characteristics, the geologic model of bedding slope is established to analyze the relationship between its stability and its geologic environment with finite element method. An overall analysis on the cut slope within a segment of highway is carded out and treatment method for the slope is put forward to meet the engineering requirement. Tne stability of all kinds of cut slope and processing project for the bedding-slip slide arc simulated. The actual test analysis results are consistent with the previous related practice results, and it proves that the methodology is reliable and superior. The research results are of significance to guide the similar work.
