【Abstract】 In this paper, the stability of fly ash under 8 degree earthquake is studied by using 3\|D dynamic effective stress analysis method. In the analysis, the 3\|D characteristic of the dam and the influence of vibrating pore water pressure on the material shear modulus are taken into account. The stability situation and most dangerous section of the dam during earthquake in different stages of construction are derived.更多还原
