摘要： 贮灰坝的稳定性分析是电厂安全运行和贮灰场安全管理至关重要的技术问题。以某电厂贮灰坝为例，采用刚体极限平衡方法对贮灰坝的稳定性进行校核，评价其稳定性，预测贮灰场达到设计库容时的稳定性。分析结果表明：该贮灰坝内外坡在现状水位和高水位运行状态下，地下水不会从外坡坡面溢出，均不会发生渗透破坏；在现状条件和贮灰达到设计容量时均是稳定的，满足贮灰库安全运行要求。通过分析可为相似贮灰坝稳定性研究提供指导，具有一定的工程应用价值。

Abstract: Evaluation of the stability of the ash storage dam is an important aspect of the safe management of ash storage yard as well as the safe operation of the power plant. This paper presents the limit equilibrium analysis method applied on the ash storage dam stability evaluation at the time when the dam reaches its full storage capacity. The results indicate that, under the current reservoir pool level and high pool level, no seepage water could be found at the downstream side of the dam slope and the seepage related damage is not likely. The safety of the current dam under current and the full storage conditions are stable and the safe operation of the dam is warranted.
