摘要
现浇综合管廊混凝土易产生一些裂缝,其中一些裂缝对结构的安全性和耐久性产生不利的影响,必须采取有效的措施对其进行防治。结合综合管廊施工中出现的裂缝进行分析,首先分析裂缝产生的原因,然后针对这些成因制定相应的措施,以预防裂缝的产生。可为设计和施工提供技术参考。
The cast-in-situ concrete of utility tunnel is easy to cause some cracks,in which some cracks will have a negative impact on the safety and durability of structure.It must be to take the efficient measures to prevent it.Combined with the cracks existing in the construction of utility tunnel,the article firstly analyzes the crack causes,and then introduces the relative measures by these causes to prevent the crack cause,which can be referred for the design and construction.
