摘要
采用有限元仿真分析等计算成果,对蔺河口工程碾压混凝土大坝温度及温度应力进行了分析,针对工程所在区气候特点,并根据大坝的实际进度及施工条件,确定了适宜的温控措施。大坝蓄水前检查,仅发现4条长度不一的表面裂缝,实践证明温控效果良好。
The analysis is made on the temperature and temperature stress for Linhekou Hydropower Station by adopting the results of the finite element emulation analysis. It determines proper temperature eontrol measures in accordance with the regional climatic characteristics, and the actual construction progress and working conditions of the dam. Only four fissures were found on the dam surface during the check prior to dam impoundment, which demonstrates good effect of temperature control.
