岩溶突泥是隧道施工和运营过程中一种常见且危害最严重的地质灾害之一,危及隧道施工的安全,影响施工的进度,破坏周围环境,结合六宜高速公路关西隧道工程在施工过程中下行线ZK40+700出现的特大岩溶突泥事故,对突泥成因进行了分析,阐述了突泥综合处治措施,并对处治全过程进行监控量测,结果表明处治后整体处于稳定状态,证明处治措施不仅理论上可靠,而且现实中安全可行,对未来岩溶隧道施工突泥处治工作有指导和借鉴作用。
Karst mud is one of the common and most serious geological disasters in the process of tunnel construction and operation, endangering the safety of tunnel construction, affecting the progress of construction and damaging the surrounding environment. Combined with the construction process of Kansai Tunnel Project of Liuyi Expressway On the ZK40 +700 occurred in large karst mud accident, the cause of the mud was analyzed, described the mud comprehensive treatment measures, and monitoring the whole process of monitoring measurement, the results show that the overall treatment is stable, that The treatment measures are not only theoretically reliable, but also safer and feasible in reality, which can guide and reference the treatment of mud in construction of karst tunnels in the future.
