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。
RCC dam with a small amount of cement, construction speed, temperature control simple, low cost and a series of advantages, which in all countries in the world have been widely developed. However, the impermeability of RCC dam is poor, and various anti-seepage measures adopted at present are not ideal. The use of hollow formwork backfill normal concrete as a seepage control solution can effectively improve its impermeability.
