以某河岸高边坡稳定性分析评价为背景,采用Slide软件计算其稳定性系数,确定其最危险滑动面;利用FLAC3D软件进行数值模拟分析,分别考虑在河流侵蚀作用和暴雨工况下边坡变形对建筑物的影响,根据位移和塑性破坏区图绘制了边坡变形影响范围线。稳定性分析结果表明,最危险滑动面在上覆填土和粉土层,河流侵蚀对边坡的变形有潜在影响,暴雨工况下边坡的变形破坏加重,对场地建筑物的地基造成影响,该分析结果与现场调查情况基本吻合。
Based on the analysis and evaluation of the stability of a bank high slope, Slide software was used to calculate its stability coefficient to determine the most dangerous slip surface. The FLAC3D software was used to carry out numerical simulation analysis respectively considering the river erosion and the deformation of the slope The impact of the building, according to the displacement and plastic damage area diagram of the slope deformation range of influence. The results of stability analysis show that the most dangerous sliding surface has the potential effect on the slope deformation in overlying soil and silt layer and river erosion. The deformation and damage of slope under heavy rain conditions aggravate, affecting the foundation of site buildings, The result of this analysis is in good agreement with the field investigation.
