坑口水库碾压混凝土坝位于福建省大田县屏山溪上,是我国已建成的第一座碾压混凝土坝,也是一座国家重点工业性试验工程。坑口坝的特点是,采用高掺粉煤灰碾压混凝土,坝体不分纵横缝,低温连续填筑,全仓面碾压,沥青砂浆防渗。这些特点在设计、施工及相应的试验研究中已得到较充分体现。本工程的设计指导思想是,在保证工程质量和节约资金、材料的前提下,尽量简化坝体结构,利于快速施工。坑口工程按五十年一遇洪
Hangou Reservoir RCC dam is located in Dapian County, Fujian Province, Ping Shan River, is China’s first built RCC dam, is also a national key industrial test project. Hangou dam is characterized by the use of high fly ash mixed with concrete, vertical and horizontal cracks regardless of the dam, continuous filling at low temperature, the entire surface of the rolling, asphalt mortar impervious. These characteristics in the design, construction and the corresponding experimental study has been more fully reflected. The design guiding ideology of this project is to try to simplify the structure of the dam as much as possible to facilitate the rapid construction under the precondition of ensuring the project quality and saving funds and materials.
