土坝地震附加孔隙水压力计入方法的探讨

The study on the calculation for the excess pore-water pressure of the earthquake on the earth dam

根据土坝的土体中孔隙水压力和有效应力与外加压力的相互关系,对地震附加孔隙水压力的产生进行了研究,从抗剪强度指标的试验方法和选取入手,分析了滑动体上作用的地震附加孔隙水压力与地震力分量的关系,提出了对地震附加孔隙水压力计入方法的计算公式。

According to the relationship between the effective stress and adding stress, the paper elaborates the formation of the excess pore-water pressure and analyzes the relationship between the excess pore-water pressure and multi-component pressure of the earthquake from the experimental method of the shear strength and points out the ealculative formations for the excess pore-water pressure.
