摘　　要：樊口二站底板混凝土采用商品混凝土,浇筑时间安排在1月初。通过ANSYS有限元三维仿真分析,原浇筑方案的底板混凝土施工期的温度应力超标。结合现场情况,经过反复试算和方案比较,最终采取预留宽缝的温控浇筑方案。该方案为实际现场施工采用,并加强表面保温,经多次检查没有出现温度裂缝。低温季节流道底板施工预留宽缝的做法可供类似工程参考。For Fankou Pumping Station,the casting of ledger wall with commercial concrete has been arranged in January. Through the 3-D simulation analysis by using ANSYS finite element software,it has been found that the temperature stress in the construction period is excessive. Considering on the real process in construction site and a great number of calculation,presetting crack is recommended as the final plan. In the construction,this plan has been accepted,and what ＇ s more,surface heat preservation has been tightened up. There is no temperature crack in the ledger wall through double-checking. The plan that presetting cracks in the ledger wall in cold periods are applicable to the similar projects.
