T型刚构0号块腹板开裂原因分析及处理

Causes Analysis and Treatment of Web Plate Crack of T-shaped Rigid Frame Zero Block

介绍了某T型刚构桥梁裂缝处理的实际案例,从发现开裂、探明开裂范围、结构计算,到开裂原因分析、后期处理,详实描述了整个处理混凝土结构裂缝的过程及方法。通过本案例,强调混凝土结构裂缝产生原因的多样性,提醒工程设计和施工人员在设计和施工各个方面主动防范裂缝的发生。

A case study about how to deal with a T-shaped rigid frame bridge crack is introduced. It de-scribed in detail the process and method of dealing with the concrete structure crack consists of five parts：discovering the crack, examining the crack range, analyzing the structure, analyzing the causes, and later-stage treatment. The case study lays stress on the diversified causes of the concrete structure crack, and urges the designers and constructors to have an awareness of the problem and avoid the problem in all of the design and construction processes.
