摘　　要：大型泵站工程进水流道混凝土极易出现裂缝。本文以洪湖东分块蓄滞洪工程腰口泵站进水流道混凝土裂缝控制工程为例,分析了工程主要技术难题,并通过有限元分析计算模型,模拟浇筑块体温控效果和方法,提出了多项应对措施。经实践,裂缝控制效果良好,可供类似工程参考。Cracks appear easily in the concrete of water inlet channel in large pumping station project. Honghu east block flood storage and detention project waist pumping station water flow concrete crack control engineering is adopted as an example in the paper for analyzing main technical problems of the project. The pouring block temperature control effect and methods are simulated through the finite element analysis and calculation model. Several countermeasures are put forward.The effect of crack control is excellent according to practice,which can be used as reference for similar projects.
