摘要

为提升川藏铁路隧道衬砌检测效率及准确性,针对其建设难度大、建设周期长、结构质量要求高的特点,分析可能引发的主要衬砌质量隐患及检测问题,从技术、管理角度提出以先进成熟、提前介入、阶段开展、信息化管理为原则的基本要求。在梳理国内外既有隧道衬砌检测项目的基础上,提出以衬砌强度、厚度、渗水情况、裂损、冻害、结构位移等为主的川藏铁路隧道检测项目及方法。通过总结近年来国内外隧道衬砌质量检测新技术,明确川藏铁路隧道衬砌质量检测应以机械化、智能化、集成化为新技术发展和应用导向,并提出川藏铁路隧道衬砌质量检测应用建议。

Abstract

Sichuan-Tibet railway tunnel has the characters of severe construction conditions, long construction period and high structure quality requirements. In order to improve the lining detection efficiency and accuracy of SichuanTibet railway tunnel, the main hidden dangers of lining quality and detecting technique problems are analyzed, and the principles of advanced maturity, early intervention, stage development and information management are proposed from the perspective of technology and management. Combing the tunnel lining inspection projects in China and abroad, the inspection list and methods for SichuanTibet railway tunnel, i.e., lining strength, thickness, water seepage, cracks, frost damage and structural displacement, are put forward. Based on the new lining quality inspection technologies in recent years, it is clear that the quality inspection method of SichuanTibet railway tunnel should be guided by mechanization, intelligence, and integration, and then corresponding suggestions are given.
