摘　　要：对某水库挡土墙破坏原因进行了详细的调查与检测,对挡土墙混凝土进行了多项检测评估与监测资料分析,同时对挡土墙结构进行了复核计算,分析破坏的主要原因。分析表明挡土墙背水面水荷载超载是造成墙体较大变形的主要原因,上部超载也对挡土墙的稳定和基底面的应力分布有不利影响,在施工中未按要求设置排水设施是破坏的直接原因。针对挡土墙破坏的现状,提出了可行的处理方案与加固措施,实践表明,修复效果良好。In order to find out the destruction reasons of a retaining wall of a reservoir, detailed investiga- tion and detection was carried out. On the other hand, the retaining wall concrete was detected, evaluated and the monitoring data was analyzed, and also check calculation of the retaining wall structure was execut- ed. It is indicated that overloading of water load on the negative side of the retaining wall is the main rea- son that gives rise to the relatively large deformation of the wall, and upper overloading also has some ad- verse effect on the stabilization of the retaining wall and the stress distribution of the foundation surface. The direct reason of the destruction is that the drainage facilities were not installed as required during the construction process. According to the current destruction conditions of the retaining wall, feasible treatment schemes and reinforcement measures are presented. It is proved that the rehabilitation effect is favorable.
