某大型复杂工程混凝土施工中变形裂缝的控制

Precaution of the deformation cracks in the concrete construction for a large-scale complex engineering

从材料与结构的角度分析了某大型客站混凝土结构地下风道施工中出现裂缝的原因并提出解决办法.表明在大型复杂工程的混凝土结构设计和施工中,在按照规范控制变形裂缝的同时,应考虑和注意施工过程中结构构件的受力状态的变化,对混凝土收缩裂缝控制也应涵盖施工全过程.

Deformation cracks in the underground duct-line at a railway station project was analyzed from the perspective of materials and structures,and the solution was presented.It showed that when large and complex engineering and massive concrete structures was designed and constructed,the deformation should be controlled with normal rule.At the same time,the variation of the force of the architecture component should be paid attention,and the control method should be taken in the entire project.
