【Abstract】 The stability of a certain ash dam under eight\|intensity earthquake is studied and analyzed using a dynamic analysis method of three\|demensional effective stress.During the analysis,the three\|dimensional characteristics of the dam as well as the effects of the formation,diffusion and dissipation of the pore water on the shear modulus of the material and the stability of the dam slip are taken into account.Finally,the stable conditions and the most dangerous sections of the ash dam in different periods are obtained by a three\|dimensional finite element program.更多还原
