1 前言混凝土面板、趾板及防渗帷幕构成了面板堆石坝工程的防渗体系,混凝土面板是面板堆石坝工程防渗重要体系中最为重要的组成部分,混凝土面板施工质量,决定着水库建成后能否安全运行。盘石头水库大坝混凝土面板采用中国水利水电第十二工程局施工科研所外加剂厂生产的 VF-Ⅱ防裂剂等外加剂的补偿收缩混凝土。盘石头水库坝址位于海河流域卫河支流淇
1 Introduction Concrete panels, plinths and impermeable curtains constitute the seepage control system of concrete faced rockfill dam. Concrete slab is the most important component of impervious system of concrete faced rockfill dam. The quality of concrete slab construction determines the reservoir After the completion of the safe operation. Panshitou dam concrete panels using the China Water Conservancy and Hydropower Construction Engineering Research Institute No. 12 Additive Factory production of VF-Ⅱ anti-crack agent and other additives compensation shrinkage concrete. Pan Shitou reservoir dam site is located in the Haihe River Wei River tributary Qi
