超长地下室温度裂缝的分析与处理
|
摘要
引起超长混凝土结构中的裂缝的因素很多,尽管混凝土的裂缝不可避免,但设计应该充分考虑各种不利因素,相对应的采取合理的措施,把裂缝控制在有害程度以内。通过对一个超长地下室裂缝的成因分析,来讨论超长混凝土结构温度裂缝的预防和处理措施等问题,为相关工程提供一定的借鉴作用。
There are many factors that cause cracks in super-long concrete structures. Although cracks in concrete are inevitable,various unfavorable factors should be fully considered in the design, and appropriate measures should be taken to control the cracks within the harmful degree. In this paper, the causes of cracks in a super-long basement are analyzed to discuss the prevention and treatment measures of temperature cracks in super-long concrete structures, and to provide some reference for related projects.
