既有线铁路隧道病害整治技术与设备发展现状

摘要

文章从隧道病害检测与安全评估、病害整治方法和工艺、病害整治材料、设备等方面对国内外隧道病害整治技术发展现状进行了系统的分析研究,提出了提高隧道设计方案的合理性、加强隧道施工过程质量的可控性、促进既有隧道病害综合整治作业规范性等建议,以供同行借鉴探讨,以期对保障我国既有线铁路隧道安全运营有所助益.%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 ma-terials and equipment. Relevant suggestions are proposed, such as increasing the rationality of tunnel design, im-proving controllability of quality in the course of tunnel construction and promoting normalization of defect remedia-tion,which can be a reference for defect remediation and safe operation in existing railway tunnels.
