摘　　要：以某电厂贮灰场为例,采用有限元强度折减法和刚体极限平衡法对火电厂贮灰坝的现状稳定性进行校核,预测贮灰场达到最终库容时的稳定性.研究表明:不管现状水位还是达到最终库容时水位,贮灰坡体地下水不会从外坡坡面流出;贮灰坝在现状条件和贮灰达到设计容量时是稳定的,能满足贮灰场安全运行要求;建议对贮灰坝体内的地下水浸润线进行观测,加强坝体外坡坡面巡视.Taking the ash yard of a power plant as an example,the stability of the ash disposaldam of the thermal power plant is calculated by the finite element strength reduction method and rigid body limit equilibrium method.The research shows that the groundwater in the ash disposal dambody will not flow out from the outer slope regardless of the current water level or the water level at the final disposal capacity.The ash disposaldam is stable when the current conditions and ash disposal capacity reach the designed capacity,and can meet the requirements for safe operation of the ash yard.It is recommended to observe the groundwater saturation line in the ash disposaldam and strengthen the inspection of the slope surface of the dambody.
