摘　　要：针对阳坡山谷灰场投运多年以来发现的坝体裂缝较多及南坝肩绕坝渗流严重等问题,在对初期坝和灰坝加高后坝体、南坝肩进行有限元静动力分析和稳定分析的基础上,对坝体和南坝肩进行了安全性评价,并对工程治理提出指导性建议,确保山谷灰场子坝加高工程的安全,同时对类似工程有一定的参考价值。Over the years of running, the valley ash yard in Yangpo was found that there were more dam cracks, and the seepage around the southern dam abutment was serious. Aiming at these problems, and based on the finite element static analysis, dynamic analysis and stability analysis on the starter dam, ash dam body heightened and the southern dam abutment, the safety evaluation were carried out on dam body and the southern dam abutment. Instructional advices were proposed for engineering control to ensure the safety of the subdam heightening project in valley ash yard, and provide a certain reference to similar projects.
