摘要
水库地震是一种复杂的地质运动。许多研究者认为水库地震是在水岩和渗压共同作用下诱发的 ,本文作者认为这还不能充分解释高震级、高频度的水库地震活动。通过研究发现在水库地震的发生过程中存在非线性共振现象 ,它和高震级的水库地震的发生有直接关系。本文从尖点突变模型出发解释非线性共振现象的本质 ,并据此进一步研究水库诱发地震的机理。
Reservoir earthquake is a complex geological movement. Many scholars think that reservoir earthquake is caused by rock-water function and infiltrative pressure function in reservoir area. The authors think that it is not sufficient to explain the reason of high degree and high frequency in earthquake. We found there is nonlinear response during the earthquake acting and it is concerned directly with high degree earthquake. The authors explain the essence of nonlinear response by catastrophic model and want to advance the research on the mechanism of reservoir earthquake.
