| 摘 要： | 地处高寒地区的冲乎尔碾压混凝土重力坝运行后多个部位出现渗水,坝体存在多处裂缝。本文以底孔坝段为例进行温控仿真分析,模拟碾压混凝土坝施工过程、混凝土分区、外界气温和温控措施等,得出大坝温度和应力的变化过程及规律。计算结果表明底孔坝段存在多处温度应力超标现象。

| Abstract: | Concentrated seepage and cracks appear in many positions of the dam after the operation of Chonghuer RCC gravity dam,which is located in alpine region. Numerical simulation of the process of construction,concrete zoning,atmospheric temperature,temperature control measures is carried out for the bottom hole section. The varying process of temperature and temperature stress and their distribution law are obtained. Numerical results show that overweight temperature stress does exist in the bottom outlet section of Chonghuer RCC gravity dam. |
