发震断层面上潮汐有效剪切应力增量的计算与加卸载的确定

发震断层面上潮汐有效剪切应力增量的数值计算是应用响应比理论的一个关键性基础问题。本文根据潮汐形变理论及弹性力学理论，导出了直接、严密和实用的潮汐有效剪切应力增量的数值计算公式，给出了判断加载、卸载区间的直接公式——潮汐有效剪切应力增量对时间-阶微分的解析表达式，最后还给出了一些应用实例。

Calculation of the Tide-effective Shear Stress Increment on the Seismic Fault Surface and Determinaton of the Load and Unload

The numeric calculation of the tide-effective shear stress on the seismic fault plane is a key to the application in the load-unload response ratio theory. The direct, strict and practical formula calculating the tide-effective shear stress increment are derived by the tidal deformation theory and the elasticity theory in this paper. The direct formula of assessing the range of the loading and unloading, the analytical-representation of the first order time differentiation of the tide-effective shear Stress increment, are also given. And finally, some application examples are shown.
