摘　　要：根据1991年完成的针对龙滩工程的大型现场试验性碾压混凝土现场取样所作的室内渗流试验的成果,初步分析探讨了碾压混凝土的渗流特性,总结了影响碾压混凝土抗渗能力的主要因素,提出了碾压混凝土施工质量及施工工艺上值得注意的一些问题。A preliminary study on the seepage characteristics of RCC is made on the basis of indoor seepage test done on the sample taken on site from the largescale testing RCC construction site of Longtan project, and the main factors influencing the seepage resistance of RCC are concluded. Problems existing in the construction quality and construction process are also pointed out.
