摘要: 下穿式隧道、超长地铁车站、建筑地下室等类似结构的侧墙混凝土裂缝问题一直是施工控制的难点,受到工程界的普遍关注。分析总结了侧墙裂缝产生的主要原因,并以某下穿隧道为例,通过一系列现场试验对不同的裂缝控制措施进行了对比,提出了一些裂缝控制措施,以期对类似工程裂缝控制提供参考。

Abstract: The cracking on the concrete sidewalls of cut and cover tunnels, very long subway stations and very deep basements of building is always one of the frequently occurred issues during the construction. This paper discusses factors that causing cracks on the sidewalls. The case history of different measures on controlling cracks on a cut and cover tunnel are presented and the results are compared. Cracking mitigation methods are also recommended.
