水库诱发地震的因素很多,水对岩石材料的影响是一个重要因素之一。从现有水库地震震例表明,水库蓄水后不是立即发生地震而往往要经过一段时间才触发地震(或地震活动加强)这可能与基岩的饱水程度有关,特别是对孔隙度小,渗透性差的库基更是如此。由于水的作用使岩石软化(岩石的粘聚力、摩擦系数,孔隙压力等产生一系列的 There are many factors that cause reservoir-induced earthquakes. The effect of water on rock materials is one of the important factors. Seismic earthquakes from existing reservoirs indicate that after the impoundment of the reservoir, it is not an immediate earthquake but it often takes a while before the earthquake is triggered (or the seismic activity is strengthened). This may be related to the degree of saturation of bedrock, especially for small porosity. This is especially true for poorly permeable Kuki. Due to the action of water, the rock softens (cohesion of rock, friction coefficient, pore pressure, etc. produce a series of
