摘 要:正For the features of high earth-rock dam constructed on the deep riverbed alluvium in the highly seismic region,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 effective stress dynamic analysis and anti-seismic safety evaluation method of earth-rock dam on deep riverbed alluviums is *** the proposed method,based on large-scale triaxial dynamic test results of soils,the acceleration and stress response,especially the earthquake-induced permanent deformation,element anti-seismic safety and slope dynamic stability of Shuangjiangkou earth-rock dam are studied and *** study results can provide valuable reference for engineering design.
