摘要
文章结合铜仁至玉屏线8处隧道的衬砌病害情况,介绍了常见隧道衬砌病害的整治措施以及相对应的数值分析方式。通过分析计算结构的安全系数,以各单元的最小安全系数为指标,探讨了在Ⅲ、Ⅳ、Ⅴ级围岩地区下经过相应的病害整治后各措施的整治效果,并分析了各措施的合理性,可为类似隧道的病害整治及效果评价提供参考。
Based on the lining diseases of eight tunnels along Tongren-Yuping line,this paper introduces the treatment measures of common tunnel lining diseases and corresponding numerical analysis methods.By analyzing and calculating the safety factor of the structure,taking the minimum safety factor of each unit as the index,it discusses the treatment effect of various measures after the corresponding disease treatment in the grade III,IV and V surrounding rock areas,and analyzes the rationality of each measure,which can provide references for the disease treatment and effect evaluation of similar tunnels.
