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。
Prestressed circular pool circumferential cracking resistance is to prevent cracking of the reservoir is an important pre-stressed pool design is an important part. In this paper, based on the revision of GB50069-2002 Code for Structural Design of Water Supply and Drainage Structures, the rules about the cracking resistance of circular ponds at home and abroad are compared. The calculation of the cracking resistance of a series of ponds with internal diameter of 30m ~ 60m, The analysis of the crack resistance of the 83 circular reservoirs in operation was carried out, and the design criteria of the anti-cracking degree were put forward.
