河道型水库蓄水诱发地震的数值模拟
Numerical study on channel reservoir induced earthquake
摘要
Abstract
We modeled the impoundment induced stress change in channel reservoir by two-dimensional finite element method. We calculated Coulomb failure stress change on the fault striking parallel to the major axis of reservoir. Compared to the regional stress field, the compressive stress caused by impoundment is small and is most confined within several kilometers depth. If the background stress is in favor of normal faulting some faults with certain dips and depths would come closer to failure,while if the background stress is in favor of shallow thrust those thrusts would be safer after reservoir impoundment.关键词
