摘　　要：为提升西藏DG水电站高寒、高海拔地区厂房结构混凝土在冬季极寒天气下的抗冻、抗裂能力,首先通过对比实验优化越冬保温材料,然后策划了一套针对该厂房混凝土越冬保温的最优适用性方案。经方案的有效落实,最终实现了高寒、高海拔地区厂房混凝土优质越冬,显著提升了混凝土抗裂、抗冻效果。DG Hydropower Station is located in high altitude and cold area.To improve the freezing and cracking resistance of the powerhouse structure concrete in the extremely cold weather in winter,the thermal insulation materials are optimized through comparative experiments,and then an optimal thermal insulation scheme is proposed and implemented.Practice shows that the cracking and freezing resistance of the concrete are significantly improved and the powerhouse concrete passes the winter safely.
