随着时间的推移 ,混凝土坝表层碳化现象日益加重。许多工程实践表明 ,采用劣质材料和较差的混凝土配合比 ,施工质量差 ,未进行表面养护 ,以及环境相对湿度较小时 ,混凝土碳化速度较快 ;有的坝在混凝土龄期 30年以后碳化趋势尚未收敛稳... 详细信息

随着时间的推移 ,混凝土坝表层碳化现象日益加重。许多工程实践表明 ,采用劣质材料和较差的混凝土配合比 ,施工质量差 ,未进行表面养护 ,以及环境相对湿度较小时 ,混凝土碳化速度较快 ;有的坝在混凝土龄期 30年以后碳化趋势尚未收敛稳定。混凝土坝的梁、柱构件因碳化引起钢筋锈蚀膨胀 ,产生顺筋裂缝和混凝土崩落的现象比较普遍。轻型平板坝因碳化严重 ,使面板挡水功能受到危害的问题 ,应引起高度重视 ,并应及时进行处理。

关键词：水工结构表层碳化综述危害性混凝土坝

＜正＞Hongjiadu （HJD） hydropower project which is located in the northern source of the main stream of the Wujiang River is the head hydropower station in the cascade projects of the Wujiang River. It is also one of the start-up projects among "west-electricity transmitted to the east" items. The gate of the diversion tunnel will be dropped down in April, 2004 and a generating unit will firstly generate electricity in July in the same year. The hydrostructures of the project consist of a dam and the structures on the left bank which conclude a spillway, a tunnel spillway, power conduit system, a power house and so on. The damsite is located in the high mountainous region with narrow valleys and karst, and the height of the dam is 179.50m. It is one of the highest concrete faced rockfill dam （CFRD） that is under construction in the world. The dam has been embanked 137m added up 7.0 million m3 at the present time and it underwent twice tests in 2002 and 2003 flood season respectively. The dam will experience the test of water storage in 2004. New technologies, such as narrow continuous plinth with equivalent width and impact compaction by LAND Pac, are adopted in the dam design and construction of HJD CFRD. The article presents the design and construction technique of HJD CFRD.
