英国土木工程结构设计标准历史悠久,较为成熟,对于给水排水结构工程有专门的规范。本文介绍了英国标准给水排水工程结构设计,内容包括强度、裂缝宽度、变形计算的基本假定、计算要求、控制指标,英标水化热和季节温差下最大裂缝宽度的估算及相关规定,分析了英标变形控制指标。在对其基本公式规定进行分析、推导的基础上,编制了英国标准的板抗弯强度及限制裂缝宽度承载能力表,并与中国国标给水排水结构设计规范的结果进行了对照,阐明了两种规范使用荷载下板的裂缝宽度计算的差异。本文可供采用英标的涉外工程参考,对于按国内标准进行的给水排水结构设计也有借鉴作用。
British civil engineering structural design standards have a long history, more mature, for the water supply and drainage structures have a special specification. This paper introduces the design of the British standard of water supply and drainage engineering, including the strength, crack width, the basic assumptions of deformation calculation, calculation requirements, control indicators, British standard heat of hydration and seasonal maximum temperature under the crack width of the estimates and the relevant provisions British standard deformation control indicators. Based on the analysis and derivation of its basic formulas and regulations, the British standard board bending strength and limit crack width carrying capacity table were compiled and compared with the results of China National Standard for Water Supply and Drainage Structure Design Code, and the two kinds Differences in calculation of crack width of slabs under normal use load. This article can be used for the reference of foreign-related projects in the British standard, according to the domestic standard for water supply and drainage structure design also have reference.
