| 摘 要： | 诱发水库地震的因素很多,而许多诱发因素都最终和库基岩体裂隙联系起来。以隐伏式裂隙为例,把水压力分为库盆水压力和渗透水压力。渗透水压力的计算采用了两个模型,通过这两个模型的计算可以清楚地了解库基中渗透水压力的传播速度。还分别阐述了这两种水压力在不同应力状态下对岩体裂隙的影响。通过研究水库蓄水后对岩体裂隙的影响可以进一步揭示水库诱发地震的机理。

| Abstract: | There are many reasons of reservoir-induced earthquake,most of them are finally associated with rock mass cranny.Concealed cranny was used as an example to analyze the question.The water pressure can be divided into osmotic pressure and reservoir pressure.By using two models to calculate the osmotic pressure,its propagation velocity could be got clearly.The effect of water pressure on rock mass cranny in different states of stress was also discussed.It was indicated that the mechanism of reservoir-induced earthquake could further be revealed by reaserching the effects of reservoir filling on rock mass cranny. |

| Keywords: | reservoir-induced earthquake mass cranny water pressure |
