Abstract: Abstract ：Based on researches on the geological environment of the construction area, the composition and the structure of the accumulation,this paper studies the genetic mechanism of the accumulation , at the same time, according to physiognomy signs of deformation and characteristics of the different components,we have disparted the different engineering geology on the basis of in-depth analysis of the basic characteristic of accumulation, on the basis of this,we discuss the causes of the talus slope and deformation mechanism of the future, mainly focus on the trigger factors which impact on the stability of the talus slope; In order to analyz the situation of groundwater activities and the influence degree of stability,the seepage simulation mainly aims at the changes of underground water level in the storm conditions;finally we evaluate on the local stability as well as the whole accumulation (distract) by using the limit equilibrium method and finite difference method, basing on the calculated results, this paper proposes corresponding prevention and disposal measures and suggestions based on the way of damage, the scale of damage and influence of the project that may be caused.
