金沙江乌东德水电站坝址高边坡稳定性研究

Study on High Slope Stability at the Dam Site of the Wudongde Hydropower Station in Jinsha River

高边坡是中国西部水电工程建设常见工程问题之一。金沙江乌东德水电站坝址两岸自然边坡高达830~1036 m,其稳定状况直接事关工程安全。以大量地质调查资料为基础,将地质宏观分析与数值分析计算相结合,研究坝址高边坡稳定性,预测工程边坡可能失稳模式,为治理工程设计提供重要依据,可作为类似工程参考。

The high slope stability is one of key engineering geological issues during the construction of water projects in west China. It is significant of the high slope stability at the Wudongde hydropower station where up to 830 - 1 036 m high to the safety of the project. According to the geological analysis and computation authors studied on high slope stability, predicted the failure model on the basis of the abundant geological study results provided an important basis for the design as well as reference for similar project. conservancy the slope is analysis the data.
