后缘蓄水系统对边坡稳定性的影响.

The loading of the trailing edge and the excavation of the leading edge will adversely affect the stability of the slope. For the engineering activities of excavation at the trailing edge of the slope to form a water storage system, a comprehensive assessment of the impact on the stability of the slope is required. This paper combines the saturated and unsaturated two-dimensional seepage field continuity equation and the stress field balance equation to establish a fluid-solid coupling calculation model. The slope water storage system excavation and the water level changes in the water storage system at the trailing edge of the slope are calculated. The leakage caused by the different storage heights results in slope stability coefficients of various working conditions such as the increase of groundwater level in the slope of the trailing edge. The calculation results show that the slope stability has a certain relationship with the excavation and storage height of the water storage system, but the impact on the stability coefficient is relatively small, and the leakage of the water storage system will significantly reduce the stability of the slope stability. Therefore, by controlling the height of the water level in the water storage system and anti-seepage treatment, it can be considered to reduce the adverse effect of the slope water storage system on the slope stability.
