龙滩水电站全断面碾压混凝土温控仿真研究及应用

Simulation Study and Application on Temperature Control for the Full-section RCC of Longtan Hydropower Station

龙滩水电站地处亚热带,高温季节持续时间长,通过对全断面碾压混凝土坝进行温控仿真研究,分析不同温控措施下的温度及温度应力状况,提出了切实可行的温控措施,使大坝提前峻工,提前发电的目标得以实现。提出的龙滩大坝全面系统的温控防裂研究成果,对于重力坝的温控防裂研究具有普遍的指导意义。

Longtan hydropower station is located in subtropical zone, the high temperature season lasts continuously 5 months in a vear. Through the simulation temperature stud？ on the full profile of the RCC dam, the analysis on the variations of temperature and temperature stress was carried out under different temperature measures and more practical proposals for temperature was put forward,this achievement supports the smooth construction of the dam and make it completed earlier than scheduled.It also laid a solid foundation for the early power genration.The achievement also has a guiding significance for the study of the crack prevention of the gravity dam.
