摘要
汶川8.0级特大地震造成了全国以四川地区为中心向外辐射的诸多水库震损,同时这次大地震也引发了对于高地震烈度区修建水库大坝一系列问题的讨论,其中包括对水库诱发地震的讨论,甚至有学者提出这次大地震与岷江上修建的紫坪铺大坝有关的论述。针对这种情况,本文分别从历史角度并结合国内外已经发生的水库诱发地震实例,明确了水库诱发地震的基本概念,论述了水库诱发地震的特点及其与天然构造地震的差别。本文最后就汶川8.0级特大地震与紫坪铺水库蓄水给出了自己的观点。
Wenchuan Ms8.0 earthquake has resulted in damage of many reservoirs in the nationwide area around Sichuang province, which leads to a series of discussion on the issue of seismic safety of dams built in high seismic intensity region. Reservoir-induced earthquake is another hot topic among this issue, and some researchers even propose the possible relation between the water recharge of Zipuping reservoir and the occurrence of Wenchuan earthquake. In allusion of this situation, we take some reservoir-induced earthquake cases as examples to illustrate the difference between natural earthquake and induced one. Finally, we put forward our points of view about Wenchuan earthquake and the water recharge of Zipingpu reservoir.
