提出采用设定地震方法对三峡库区地震进行了危险性评估,其条件为水库诱发地震与构造地震同时存在。研究结果表明:设定地震类型对于滑坡安全系数各类特征值影响明显,设定地震位置对于黄土坡滑坡稳定性具有重要影响。
A scenario earthquake method is proposed in order to evaluate the seismic risk in the region of the Three Gorges project under the condition that reservoir induced earthquake and tectonic earthquake exist simultane- ously. The results show that the scenario earthquake type affects all kinds of eigenvalue of the safety factor of land- slide obviously and scenario earthquake location affects the stability evaluation.
