从岩石水力学观点探讨水库诱发地震机理

摘要

水库诱发地震机理的研究目前还停留在定性的层面上,没有进行系统的理论推导和计算.本文从岩石水力学观点出发推导了水体荷载、孔隙水压力和水岩物理化学作用诱发地震的数学模型,并以丹江口水库为例进行了计算,得出了一些很有价值的规律,为水库诱发地震机理研究提供了理论指导.%Study on the mechanism of reservoir induced earthquake has just stayed at the qualitative level so far without systematic theoretical derivation and calculation. In the paper,the mathematical models of induced earthquake,which are lured by water load,pore hydraulic-pressure,physical and chemical effects of water and roch,were deduced and have been verificated with the Danjiangkou Reservoir. Some valuable rules were drawn through calculating, which provides theoreticalguidance for the mechanism research of reservoir induced earthquake.
