| 摘 要： | 根据断裂力学原理，研究了水库蓄水后，在原有产生断裂的地应力基础上库水产生的附加应力，并分析了张开和闭合断裂的应力强度因子的变化趋势和正断层、逆断层及走滑断层发生扩展的可能性，从而揭示不同断层诱发水库地震的可能性。

| Abstract: | Applying fracture mechanics principle, this article has studied reservoir water-induced appended stress on the basis of original fracture-induced stress of rock after reservoir is filled with water and analyzed changing tendency of opening and closing fracture tress intensity factor and expansion probability of positive, negative and sliding faults. Thereby the probability of different kinds of faults-induced reservoir earthquake will be revealed. |
