天津尔王庄水库粉土、粉砂层动力变形和孔压累积特性分析

Study on properties of dynamic deformation and cumulation of pore water pressure of silt and silty sand at Erwangzhuang Reservoir in Tianjin

通过室内应力控制振动三轴试验,分析研究了尔王庄水库坝基内存在着的粉土层和粉砂层的动力变形和孔压累积特性,以此分析坝基土及大坝整体抗震稳定性.

The dynamic deformation and the cumulation of the pore pressure of the silt layer and the silty sand layer in the foundation of Erwangzhuang Reservoir in Tianjin are analyzed and studied through the indoor stress controlled vibrating triaxial test, with which the seismic stabilities of both the foundation soil and the dam body are analyzed.
