摘要

针对强震区深厚覆盖层上土石坝工程的特点，基于土石料三维粘弹塑性动力本构模型，考虑孔隙水压力消散和扩散，建立了深厚覆盖层上土石坝地震反应分析的三维真非线性有效应力动力分析方法及抗震安全评价方法。利用土石料动力特性的大型三轴试验成果，对一深厚覆盖层上的土石坝进行了地震反应分析，给出了坝体及覆盖层地基的加速度反应、应力反应，并结合单元抗震安全系数、防渗墙动应力、地震残余变形、坝坡动力稳定性等进行了抗震评价，为大坝的抗震设计提供了有力的技术依据。

Abstract

based on the proposed 3-D elasto-viscoplastic dynamic constitutive model of soil

and considering the dissipation and diffusion of seismic pore water pressure

a 3-D authentic nonlinear method for effective stress dynamic analysis and anti-seismic safety evaluation is presented to study the anti-seismic safety of earth-rock dam on deep riverbed alluviums. Using the proposed method

based on large-scale triaxial dynamic test results of soils

the acceleration and stress response

element anti-seismic safety and slope dynamic stability of one earth-rock dam are studied and evaluated. The study results can provide valuable guide for engineering design.
