| 摘 要： | 系统分析了三峡井网8口井水位对汶川8.0级地震的同震响应及其后效特征，揭示出这些特征因井而异，其差异性在井孔结构相似的条件下主要取决于井点的构造部位、观测含水层的地下水埋藏类型、含水层的导水系数等条件；深入研究了井水位同震后效特征中残留阶升与阶降的力学含义及其地震预测意义，并用仙女山断裂带上近期地震活动验证了残留阶升区可能是未来地震危险区的科学推论．

| Abstract: | We systematically analyzed coseismic well level response in Three Gorges well-network and its post-seismic characteristic to MS8.0 Wenchuan earthquake. The result indicates that each well has its characteristic of itself. In the condition of similar borehole configuration, the difference lies on site structure of the well, imbed type of monitoring layer, transmissivity of aquifer system. We studied mechanical mechanism of coseismic and post-seismic step-rise and step-drop, and its significance in earthquake... |
