摘　　要：碾压混凝土坝表面防护是防止表面裂缝的重要措施.通过现场试验和计算分析,为工程提出合理的保温保湿方案提供了依据,进而研究了喷涂聚氨酯的碾压混凝土坝的施工仿真,并和实测结果进行了对比.研究表明:在大坝表面喷涂聚氨酯泡沫材料具有良好的保温保湿效果,施工仿真分析和实测结果吻合良好.An important measure to prevent surface cracking is to protect the surface of roller compacted concrete dam.This paper advanced a reasonable program for thermal insulation and moisture holding through the field test and calculation analysis.Simulation analysis of a roller compacted concrete dam is carried out and compared with the results of experiment.The results show that the polyurethane foam has fairly good properties of thermal insulation and moisture holding.The results of simulation analysis during construction are in good agreement with field test data.
