摘　　要：小湾水电工程具有高坝大库的特点,坝身导流底孔封堵工程质量要求较高,施工中采取多项针对性的措施进行截水墙施工、温控混凝土浇筑、回填灌浆、接缝灌浆以及补充化学灌浆处理渗漏,成功地完成了大坝导流底孔封堵工作,诸多措施可作为类似工程的参考。Xiaowan Hydropower Project has the character of high dam with large reservoir,and then the requirement on the construction quality of the plugging of the diversion bottom outlet of the dam is higher;for which several pertinent measures are adopted during the construction for the cutoff construction,concrete placement under temperature control,backfill grouting,joint-grouting and the additional chemical grouting for the treatment of leakage,etc.In this way,the plugging of the diversion bottom outlet of the dam is successfully completed;from which some construction measures can be taken as the references for the similar projects concerned.
