山西省某高填方路基边坡稳定性分析

摘要

According to boundary conditions, morphological conditions and deformation tendency of the high-filling subgrade in Shanxi province, the paper establishes reliable finite element model, studies the landslide stability, and finds out that:the landslide will be instable under natural condition, and the maximum deformation of x direction( along the direction of sliding surface) is about 8 cm;the maximum deformation of z di-rection(vertical direction) is 5. 8 cm. Therefore, it is necessary to reinforce the slope stability.%根据山西省某高填方路基边坡的边界条件、形态特征和变形趋势,建立了经验可靠的有限元模型,并对该处滑坡的稳定性进行了深入研究,研究得出,在自然状态下,滑坡体有失稳的危险,x方向(沿滑动面方向)位移的最大变形量为8 cm,z方向(垂直方向)的最大变形量为5.8 cm,有必要对边坡进行稳定性加固处理。
