混凝土面板堆石坝病害特点及其除险加固
Analysis on CFRD defect′s characteristics and its reinforcement
摘要
Abstract
In recent years,the CFRD construction in China has obtained outstanding achievements;however,various dam de-fects appeared in the passed 30 years such as compression failure of slab,slab crack,slab subsidence,water sealing failure, earthquake damage,etc,and some dams are in serious seepage condition,which threaten the dam safety significantly.Through the typical reinforcement engineering practices in Baiyun dam and Zhushuqiao dam in Hunan Province,we summarize the charac-teristics of CFRD defects,and put forward comprehensive reinforcement measures including dense grouting for loose layers,filling grouting for slab void,patching for damaged slab,repairing water sealing.These measures could provide reference for CFRD re-inforcement.关键词
