以云南大理~丽江高速公路的控制性工程——花椒箐隧道为工程背景,对该隧道的右幅丽江端K40+113里程涌水突泥的综合处治进行论述,对工程概况及隧道病害的发生情况进行介绍;对涌水突泥发生的机理进行分析;详述该病害的综合处治方法、过程及效果;最后,结合该病害的处治过程总结出隧道施工过程中预防涌水突泥病害的细节措施及施工注意事项。经过处治,花椒箐隧道顺利通过了该涌水突泥段,最终建成了目前云南的第一长隧,该病害的成功处治可为类似工程提供较好的借鉴经验。
Taking the control project of Dali-Lijiang Expressway in Yunnan Province as the background of the project, the comprehensive treatment of K40 + 113 mileage gushing mud at the right Lijiang River side of the tunnel is discussed. The project overview and the occurrence of tunnel diseases The mechanism of gushing mud was analyzed, the comprehensive treatment method, process and effect of the disease were described in detail. Finally, the detailed measures and construction of prevention of gushing mud and mud in the process of tunnel construction were summarized based on the treatment process of the disease Precautions. After treatment, the tunnel of pepper jelly passed the gushing mud section and finally built the first long tunnel in Yunnan at present. Successful treatment of the disease can provide a good reference for similar projects.
