摘要： 为深入研究带裂缝隧道衬砌安全性评价的方法及裂缝处治技术，基于隧道衬砌裂缝调查结果，利用综合判定法对带裂缝隧道衬砌段的安全性进行了全面评价，同时利用刚度退化理论对 带裂缝隧道衬砌结构的安全系数进行了验算，在此基础上，采用埋管注浆法和“钢拱架+注浆锚杆”法有针对性的对不同安全性的带裂缝隧道衬砌段进行了处治。研究结果表明:综合判定法融 合了各单指标评价体系，使其对带裂缝衬砌安全性评价结果更加全面、客观、准确；利用刚度退化理论对带裂缝隧道衬砌安全系数验算结果与安全性评价结果基本吻合，二者共同为带裂缝隧 道衬砌的处治提供了理论依据；采用埋管注浆法和“钢拱架+注浆锚杆”法对不同隧道段有针对性的进行处治，可取得良好的效果。

Abstract: In order to study the safety evaluation method and treatment technology of tunnel lining with cracks in detail, the overall evaluation of the tunnel lining with cracks was carried out by the comprehensive assessment method, which was based on the research result of tunnel lining cracks. At the same time, the safety coefficients of the tunnel lining with cracks were checked by the theory of stiffness degradation. On the above basis, the “burying pipe and grouting” method and “steel arch centre and grouting bolt” method were adopted to treat tunnel lining with cracks with different safety. The results show that the comprehensive assessment method merges various single evaluation index systems, therefore, its safety evaluation on the tunnel lining with cracks is more comprehensive, objective and accurate. The check result of safety coefficients of the tunnel lining with cracks obtained by the theory of stiffness degradation coincides with the result of safety evaluation, and these two results provide theoretical basis for the treatment of the tunnel lining with cracks. Different tunnel sections are targeted for treatment by using the “burying pipe and grouting” method and “steel arch centre and grouting bolt” method, which has a good effect.

Key words: tunnel engineering, tunnel lining with cracks, safety evaluation, stiffness degradation theory, treatment technology
