| 摘要: |
| 在较大的混凝土建筑物中为防止因地基不均匀沉降及温度变形造成破坏，常设有伸缩缝；而且由于分期施工大体积混凝土均设有施工缝。此类人工缝不同于裂缝，但处理不好，同样会产生较大的病害，恶化建筑物的运用条件，甚至危害结构的安全。本文结合参窝、观音阁等水库，对病害进行了分析，同时介绍了上堵下排、区域防渗等修补措施及效果，为其他类似工程提供了借鉴。 |

| Abstract: |
| This paper analyses the disadvantage of large volume concrete expansion joint and construction joint with the facts of Shenwo,Guanyinge Reservoirs. At the same time,it introduces the mending effects of choking up-draining down and regional seepage prevention. So that it can proveide a reference for the similar projects. |
