超长地下室混凝土结构裂缝综合控制探讨

Research of cracks control in the super-length basement concrete structure

本文通过分析某超长地下室混凝土结构顶板裂缝形成原因及受力机理,阐述在超长地下室混凝土结构设计及施工过程中应注重温度应力对其裂缝的影响,提出防止超长混凝土结构裂缝综合控制的措施,供设计、施工人员参考。

In this paper, the reason and mechanism about the crack of the basement＇s roof of the super--length concrete structure is discussed. Thinking about the influence of the temperature stress to the crack of super--length concrete structure, the method of cracking control during construction is discussed as the reference in designing and construction.
