葠窝水库大坝由于施工缺陷和冻融、渗漏、汽蚀等破坏，溢流坝面混凝土严重剥落。在水库加固工程中，应用具有粘结强度高、干缩量小、抗裂性能强等特点的聚合物砂浆，对大坝溢流面混凝土剥落薄层进行修复，取得了良好效果。该工程在东北寒冷地区应用聚合物砂浆大面积、全孔段修复溢流坝面具有一定的创新，可供其它类似工程设计施工方案时参考。

The concrete of Shenwo reservoir dam spillway is severely peeled due to masons such as construction defects, leakage, freezing, thawing, cavitation, etc. The characteristics of high bonding strength, small drying shrinkage and excellent crack resistance of polymer mortar are utilized sufficiently to repair the thin layer parts with concrete peeling on the dam spillway, and excellent results were achieved. The project applies polymer mortar in thin layer of dam spillway in full hole section and larger area in the frigid northeastern region, which has certain degree of innovation, thereby providing experience and lessons for similar projects.
