【摘要】 <正> 一、引言水库诱发地震,多数学者认为是蓄水作用促使浅部地壳构造应力或岩体自重应力释放的结果。研究表明,诱震概率随水库规模的扩大而增加,大Ⅰ型水库(库容大于10×10~8m~3)诱震概率约12％,超大型水库(坝高大于200m)的诱震概率高:达28％;60年代以来,世界范围内主要水库诱发地震有中国广东新丰江水库地震(M_S=6.1,1962.3)、赞比亚卡里巴水库地震(M_S=6.1,1963.9)、希腊克里玛斯塔水库地震(M_S=6.3,1966.2)及印度柯依那水库地震(M_S=6.5,1967.12)等6级以上地震,促使人们更多地探索其诱震机理和预测问题,目前这一过程的探索仍处在资料积累阶段。许多更多还原

【Abstract】 At present research on reservior induced seismicity has been at exploratory and material accumulating stage. The appraisal methods include mainly, seismicity, analogy of geology and probability statistics. etc. In this paper, the possibility of induced seismicity was analysed by analogy according to the condition of reservior in the Xiang Jia Dam area, and contrast with analogy, which gained more identical result.更多还原
