摘要
针对铁路运营过程中衬砌混凝土频繁出现的空洞、欠厚、强度不足、裂缝、不密实及钢筋和钢拱架分布不均匀等缺陷,通过多种检测手段及时、准确地找到可见的或隐蔽的衬砌质量缺陷和病害,为隧道缺陷修补和病害处置提供精确数据,保障铁路通车运营安全。
In view of the defects of lining concrete,such as cavity,underthickness,understrength,crack,uncompacted and uneven distribution of reinforcement and steel arch,which frequently occur in the process of railway operation,visible or hidden lining quality defects and diseases can be found timely and accurately through various detection methods,so as to provide accurate data for the repair and disposal of tunnel defects and ensure the safety of railway operation.
