水文地质结构与水库诱发地震

Hydrogeological structure and reservoir induced seismicity

本文基于断层渗透结构和岩体渗透稳定性两个概念,提出了水文地质结构及其分类方案。通过理论分析和水库地震案例解析,阐述了水文地质结构对诱发地震的制约作用。提出了基于水文地质结构进行水库诱发地震危险性评价的思路。对水库诱发地震危险性评价具有一定借鉴意义。

Two concepts, i.e., fault permeability structure and rockmass seepage stability, are introduced into the formatting hydrogeological structure. The constrain mechanisms of the hydrogeological structure on reservoir induced seismicity (RIS ) are also discussed in this paper. Based on theoretic analyses and RIS case studies, a kind of methodology of RIS risk assessment is proposed.
