水力扩散与水库诱发地震关系的讨论

DISCUSSION ON RELATIONSHIP BETWEEN THE HYDRAULIC DIFFUSION AND RESERVOIR-INDUCED EARTHQUAKE

本文讨论了水力扩散和水库诱发地震与水文动力地质条件之间的联系,提出了水力扩散是水库诱发地震的主要原因。本文还建立了两个与水力扩散相联系的诱发震源模型——非应力增长模型和应力调整模型,並给出了该模型在水库地震预报中的应用条件和方法。

In this paper we have discussed the relations between the hydraulic diffusion, reservoir-induced earthquake and dynamic geological conditions in hydrology. We suggest that the hydraulic diffussion is main cause of reservoir-induced earthquake. We have also constructed two iducedfocus models associated with the hydraulic diffusion——nonstress increasing model and stress adjusting model, and proposed conditions and method of applying those models in prediction of reservoir-induced earthquake.
