英文摘要	Hydrodynamic condition as saturated seepage flow is one of the most important factors to cause instability of slope mass in the mountain area. On considering the movable characteristics problem of straight slope mass under different seepage discharge, the paper firstly built the movable seepage model of straight slope, then analyzed the hydraulic effect of slope body and taken mechanical analysis to get the mechanical formulas, last dissected the movable variation of straight slope under different seepage discharge by applying hydraulics theory and limit equilibrium method. Further, to check the formulas, the paper take meizoseismal area-Guojuanyan gully which locates at Dujiangyan as an example, analyzed the heights of seepage flow change with seepage discharge, the hydraulic characteristics of the inner slope and the movable variation of straight, slope under seepage discharge. Results indicate that the failure and movement of straight slope is due to increasing of the seepage discharge which deteriorates the hydro-environment abruptly, moreover, seepage force come from water head difference promotes the possibility of straight slope to fail which provided a favorable condition for the mixture of seepage water and sediment to transfer to debris flow.
