摘　　要：为保证兰新线妖魔山隧道内电气化改造顺利实施,采用地质雷达检测、现场调查等方法对隧道结构运营状态进行全面检测和评估。检测结果表明,该隧道不存在影响电气化挂网的衬砌内部及其背后空洞,但存在衬砌裂损、局部混凝土剥离、渗漏水等病害。分析病害产生的原因,采取堵排结合的方法,对隧道衬砌裂损和渗漏水进行综合整治,可为类似工程提供参考。In order to ensure the electrification reform implementation of Yaomoshan tunnel in Lanxin line,this paper conducted a comprehensive inspection and evaluation of tunnel structure operation state by adopting such methods as geological radar detection,field investigation,etc. Test results showed that there are no cavities which may affect electrified netting inside and behind the lining,but the diseases including lining cracking,local concrete peeling,water leakage are found in this tunnel. This paper analyzed the causes of diseases,applied the sealing and drainage approach and made a comprehensive treatment of tunnel lining crack and water leakage,which could provide a reference for the similar projects.
