摘要
从天生桥一级水电站大坝观测资料入手 ,分析出高混凝土面板堆石坝发生面板结构性裂缝和面板脱空的主要原因是由于面板未得到坝体的均匀可靠的支撑 ,为此从设计、施工等多个方面 ,提出防止面板结构性裂缝的措施 ;并认为设计要贯穿于整个施工过程中 ,才能防止面板发生结构性裂缝。
Studied and analyzed dam observation data of Tianshengqiao ⅠHydropower Station, the main reasons of occurring structural cracks on the face and the face separated from the body of high concrete face rockfill dam are that the face could not be supported evenly and reliably by the dam body. Therefore, some measures of prevention on structural cracks occurring on the face slab are raises from many aspects such as design, construction and etc. And in order to prevent on structural cracks occurring on the face, design must be run through whole construction process.
