摘　　要：预应力圆形水池的环向抗裂度是防止水池开裂的重要保障,是预应力水池设计的重要内容。本文结合《给水排水工程构筑物结构设计规范》(GB50069-2002)的修编,比较了国内外规范有关圆形水池抗裂度的规定,对内径30m^60m一系列水池进行了抗裂度计算,对收集到的83个正在运行的圆形水池进行了抗裂度分析,并对其抗裂度设计标准提出了建议。The circumferential crack resistance of prestressed circular water tanks is an important safeguard to prevent cracks on tank wall and a key part of tank design.In this article,incorporating the revision of Structural Design Code for Special Structures of Water Supply and Waste Water Engineering（GB50069- 2002）,comparison was made between domestic and overseas provisions on crack resistance of circular water tank;calculations for a number of tanks with diameter between 30 m and 60 m were conducted;crack resistance analysis for 83 items of tank projects in operation were carried out;and finally some recommendations on crack resistance design criteria were given.
