摘要：

Baling River bridge is located in the alpine gorge area. Its west bank is a dip slope with 300 m height. In order to ensure the bridge construction and operation, it is important to analyze the slope stability under the condition of rain, bridge load and earthquake. Firstly, characteristics of the west bank slope were studied such as the structure type, the combination of structural plane and slope surface, the weathering of rock mass and the physical and mechanical properties. Secondly, based on the slope rock mass quality classification, the slope stability was analyzed under rain. Finally, the slope engineering effect under slope gravity, bridge load and earthquake was researched by FLAC3D numerical simulation software. It is concluded that the site is suitable for building bridge.
