摘要
南宁地铁2号线工程施工过程中频遇岩溶难题,结合某盾构隧道区间的施工现场实际情况,提出了盾构隧道岩溶处治的原则和范围,分别从溶(土)洞处理和岩溶突水、突泥的应急处理2方面进行岩溶处治方案分析,并采取技术手段对处治效果进行检测及分析,确保了盾构施工顺利通过岩溶地段。
During the construction of Nanning Subway line 2, karst problems are often encountered, combined with the actual situation of a shield tunnel construction site, the principle and scope of karst treatment of shield tunnel are put forward. The karst treatment scheme is analyzed from two aspects as karst （soil） cave treatment and karst water inrush and emergency treatment of mud outburst. This paper takes technical measures to detect and analyze the treatment effect, and ensures that the shield construction passes through the karst area smoothly.
