摘要
针对高铁隧道衬砌出现的裂缝病害,通过对隧道秋检资料的统计分析和隧道的现场调研,初步掌握了隧道裂缝的分布规律。裂缝作为隧道衬砌常见病害,从混凝土自身特性、基础不均匀沉降、施工因素、列车动荷载作用、空气动力学效应等方面进行分析,并考虑高铁隧道的特殊性,从空气动力学效应方面进行探讨。提出隧道衬砌裂缝的形成大多是多种因素的共同作用,建议隧道裂缝整治时,应先确定病害的主要成因再进行整治。
Aiming at the crack disease of high speed railway tunnel lining, the paper preliminarily grasps the distribution rule of tunnel lining through the statistic analysis of the tunnel inspection in autumn and the field research of the tunnel. Crack being a common disease, the paper analyses it from the aspects of concrete properties, differential settlement of the base, construction factors, train dynamic load effect and aerodynamics effect. In view of the particularity of high speed railway tunnel, the paper makes a study from the respect of aerodynamics effect. The paper puts forward that tunnel lining crack is caused by various factors and that the maior causes should be confirmed before remediation.
