Abstract The state of the art of the techniques and development tendency of defect remediation for existing railway tunnels are studied in terms of defect detection and safety evaluation, treatment methods and technology, adopted materials and equipment. Relevant suggestions are proposed, such as increasing the rationality of tunnel design, improving controllability of quality in the course of tunnel construction and promoting normalization of defect remediation, which can be a reference for defect remediation and safe operation in existing railway tunnels.
