盘石头水库混凝土面板堆石坝面板防裂技术研究

Face plate anti-splitting technology for concrete rock-mound dam in Panshitou reservoir

淇河盘石头水库是河南省"九五"重点建设项目,大坝坝型采用混凝土面板堆石坝。大坝面板混凝土的配合比设计,采用补偿收缩技术,达到了设计的抗冻、抗裂要求,大坝一期面板未发现一条裂缝。这是我国北方寒冷地区首次采用该技术,为混凝土面板的防裂研究提供了借鉴和经验。

Qihe Panshitou reservoir is the key construction project of '95' in Henan province.The dam type adopting the concrete face stone rock dam.The face concrete mixture ratio design adopting compensation contract technology has reached design requirement of frost resisting and crack resistance.The first phase face plate of dam wasn't discovered any crack.This technology is adopted for the first time in the north cold area of our country,which is refered to the study of concrete face plate.
