摘 要:丰满水电站大坝全面治理(重建)工程是对松花江干流上原丰满大坝进行重建,重建工程为碾压混凝土重力坝,最大坝高94.50 m,坝体体型与丰满老坝较为接近。由于工程地处东北严寒地区,气候条件恶劣,坝体体型大,混凝土的温控防裂难度较大。稳定温度场是确定坝体混凝土温控标准和温控措施的基础,本文通过有限元仿真计算确定新建坝体的稳定温度场,并与老坝坝体实测温度进行了对比,说明新建坝体稳定温度场的计算结果与老坝实测温度结果基本一致,可以作为确定坝体混凝土温控标准和温控措施的依据。The Fengman hydropower station dam comprehensive management(reconstruction) project is the reconstruction project for the old Fengman dam on the main songhuajiang river. The reconstruction dam is a roller compacted concrete gravity dam, its maximum dam height is 94.50 m and the dam body type is similar to the old dam. There are great difficulty in the temperature control and crack prevention of the concrete because the large dam body and poor climate conditions in cold region of Northeast China.The stable temperature field is the basic for determining the standard and measure of the temperature control. The stable temperature field of the new dam body is calculated and determined by using finite element simulation, and compared with the observed temperature of the old dam body. The calculation result of the stable temperature field of the new dam body is basically identical with the observed temperature of the old dam, which could be used as a basis for determining of the standard and measure of the temperature control.
