黄山-米山断裂活动性及其对米山水库稳定性影响的评价

Evluation to Fault Activity of Huangshan-Mishan Reservoir Fault and Its Effect on Stability of Mishan Reservoir

摘要:

由野外观察资料证实 ,黄山米山断裂是挤压逆冲为主兼左旋走滑断裂。该断裂中更新世晚期以来没有活动 ,内部物质固结较好 ,且断裂不从坝区通过 ,对米山水库的稳定性不会造成大的影响。

Abstract:

As proved by field investigation informtion, it is regarded that Huangshan-Mishan fault was formed by push and thrust function with left-lateral slip. It has been activeless since late period of medium Pleistocene, and interal materials have good consolidation. As the fault doesn′s go through dam area, it will not make great effect to Mishan reservoir.
