摘　　要：碾压混凝土坝具有水泥用量少、施工速度快、温控简单、工程造价低等一系列优点，因而在世界各国得到广泛发展。然而，碾压混凝土坝的抗渗性较差，目前采用的各种防渗措施也不甚理想。采用空心模板回填常态混凝土作防渗体方案，能有效提高其抗渗性。The RCC dams riave been widely built and developed in the world, thanks to their strong points including not much of cement content, rapid construction, simple temperature controI, lower costs, and so on - However, the RCC dams have poor impermeability and the seepage control measures used so far are not satisfactory. The hollow forms filled with conven tional concrete, as a impermcable body, can improve effectively impermeability of the RCC dam.
