摘　　要：水池池壁一次性浇筑混凝土方量太大会使水池池壁混凝土开裂程度过大,影响结构安全和正常使用;一次性浇筑混凝土方量太小会增加施工时间,拖延工期。针对该问题,本文分析了混凝土裂缝的成因,结合工程实例选择三维有限元水池设计软件建立模型,对极端气候条件下大型水池混凝土一次性浇筑不同混凝土长度所产生的裂缝宽度进行计算和分析,确定了本案例最佳浇筑长度为24.2m,其计算方法可供其他大型清水池池壁混凝土浇筑工程参考借鉴。Too much one-time concrete pouring amount of pool wall increases concrete, affects structure safety and normal use, hut too little one-time concrete pouring amount increase construction time. Aiming at this issue, causes of concrete cracks is analyzed, calculation and analysis of crack widths caused by different one-time pouring concrete lengths of large-scale pool under extreme weather conditions are carried out by a 3D finite element pool design software according to a project example. The optimal concrete pouring length of this example is 24.2 m, and the calculation method of this project can be used as reference for the concrete pouring of the other large clear water pool.

关 键 词：裂缝成因 裂缝宽度 最佳浇筑长度
