摘要
在外荷载作用下，水工锅筋混凝土构件常需进行抗裂或限制裂缝宽度的验算。本文针对裂缝计算中的若 干同题．例如验算时的取值标准，最大裂缝容许值，裂缝对钢筋锈蚀的影响分析等问题进行深入探讨．最后提出在施 工中减少裂缝的技术措施。
The checking computation of anti - crack and limiting crack opening for hydraulic re- inforced concrete element is needed under external load. The paper discusses some questions of fissure computation, for example, taking value standard of checking computation, allowable value of maximal fissure and the influence of fissure to reinforcing bar corrosion, and puts forward the technical measures for reducing fissure during the construction.
