金沙江虎跳峡河段水电开发重大工程地质问题研究
|
摘要
虎跳峡河段水电开发效益显著,具备建设金沙江中游龙头水库的地形、地质条件。本河段水电开发涉及的重大工程地质问题有:强震区建坝问题、河床深厚覆盖层建高坝问题、坝肩及近坝大型堆积体稳定问题、大型洞室群的围岩稳定性以及工程高边坡稳定问题等,研究这些重大工程地质问题对本河段水电开发方案比选意义重大。
There are significant benefits of hydropower development of Tiger Leaping Gorge, justifying the construction of Jinsha River Reservoir in the middle reaches with leading topographical and geological conditions. The hydropower development involves major engineering geological problems: dam-building in earthquake zone, dam-building under riverbed deep cover, large accumulation body stability near abutment and dam, large-scale stability of surrounding rock caverns as well as the high-slope stability, etc. Studies on those problems are of great significance to hydropower development projects of Tiger Leaping Gorge.
