The present digital water level recording may possibly lose some information,so large earthquake caused abnormal change of water level recorded by analog recording is clearer than that by.

认为：目前的水位模拟记录较数字化记录能更清晰地看到巨大地震引起的水位异常变化过程；大震引起的水位上升和下降可能是地震波的作用改变了构造单元的应力所致，并与井点的地质构造部位有关；同一井孔对同一断层上破裂方式一致的大地震的响应方式是一致的，只是对震级大的地震响应幅度大，震级减小，响应幅度亦减小

Based on the laminate theory, a laminate weakened by damage is treated as an anisotropic thin plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, the series solution of finite anisotropic thin plate containing an elliptical inclusion is proposed with the help of Faber series. A hybrid element with an elliptical inclusion for anisotropic materials is obtained by using the hybrid variable principle, and the element efficiency is verified by numerical examples. The state of the damage is modeled by an elliptical soft inclusion, and using the point stress criterion based on characteristic curve and Yamada-Sun etc. criteria, the prediction of the strength of a composite laminate with damage is set up. The effects of various parameters on the stress distribution and the residual strength of a composite laminate weakened by damage are detailedly studied.
