| 摘 要： | 根据洪口水电站碾压贫胶砂砾料围堰施工实践和中国水利水电科学研究院等单位在贵州黄花寨水电站进行的碾压混凝土坝大层厚现场试验成果，对按碾压层厚50cm施工碾压混凝土大坝的可行性进行探讨，并提出大坝上游变态混凝土采用掺HF外加剂拌制，增大坍落度，降低变态混凝土振捣难度，使变态混凝土更均匀密实，并增加混凝土强度的设想。

| Abstract: | Based on the construction of miler compacted lean cement aggregate used for the cofferdam of the Hongkou Hydraulic Power Station and the in - situ test results of RCC dam layer thickness of Guizhou Huanghuazhai Hydraulic Power Station carried out by China Institute of Water Resources and Hydropower Research, etc., this article discusses the possibility of RCC dam construction with layer thickness of 50 cm, and puts forward the proposal of increasing slump, reducing the difficulty of abnormal concrete vibrating and making abnormal concrete more uniform and compact by adding HF additive in upstream abnormal concrete. |
