Abstract

Abstract

Erman mountain landslide of Han Yuan County as the example, according to the exploration of landslide site conditions and indoor test of soil parameters; Choosing a built-in VBA for development tool to develop the side (slip) slope stability analysis plug-in based on ArcGIS, which makes the study regional risk zoning assessment diagram. Results show that the special topographical condition, geological structure after the earthquake, continuous heavy rains filled water load, slope unsaturated seepage flow, increasing the pore water pressure and rapidly reducing the soil matrix suction, leads to the shear strength decreased of the slope slip plane in the soil and finally landslides. Risk zoning evaluation chart of research area based on ArcGIS and the actual situation of slide have goodness of fit. Research result provides a new way for further analyzing the effect on side slope (slip) and warning under heavy rainfall condition.
- earthquake slope,
- rainfall,
- landslide,
- stability assessment,
- intuitive forecasting
