摘要： 从岩石的应变与应力的非线性响应分析了体应变固体潮加卸载响应比的物理机理, 给出了体应变固体潮加卸载响应比的计算方法,并以昌平和峰峰台的体应变观测值为例,计算了二台的体应变固体潮加卸载响应比。结果表明,在中强地震前存在增大变化。

Abstract: In this paper, based on the no nlinear response of rock strain and stress, we have analized the physical mechanism of loading and unloading response ratio of the earth tides of, bulk strain, and the calculation method of loading and unloading response ratio of the earth tides of bulk strain is given. We took the observed values of the bulk strain at the Chang ping and Fenfeng stations as example, calculated the loading and unloading response ratio of the earth tides of bulk strain. Before the moderately strong earthquake the response ratio has shown the variation of increase.

Key words: Bulk strain, Earth tide, Loading and unloading response ratio
