根据崩滑体的基本特征和地质条件,采用有限元软件ANSYS10.0,运用强度折减法在自然和连续暴雨两种状态下对崩滑体进行了模拟计算,确定了两种状态下崩滑体的安全系数与滑动面。根据地质勘查和数值模拟结果,确定小南海崩滑体整体处于基本稳定至稳定状态,但其前缘有可能发生滑塌,同时现有地形改变后,崩滑体仍有整体失稳的可能。分析了导致边坡稳定性下降的因素并提出了生物措施和工程措施相结合的防治方案,为崩滑体治理提供了依据。
According to the basic characteristics of the landslide and the geological conditions, finite element software ANSYS10.0 is used to simulate the landslide under both the natural and continuous rainstorms by strength reduction method. The safety factor and sliding surface. According to the results of geological survey and numerical simulation, it is confirmed that the Xiaonanhai landslide is in a stable and stable state as a whole, but the slip of the leading edge may occur. At the same time, the existing landslides may still have the possibility of overall instability. The factors leading to the decline of slope stability were analyzed and the combination of biological measures and engineering measures was put forward to provide a basis for the landslide control.
