毛家岩溶隧道溶洞处理技术

摘要

结合毛家隧道溶洞处理实例,对溶洞实际情况进行了考察了解,在此基础上因地制宜地采取相应措施对淤泥层软基进行了处理,论述了高压旋喷桩施工及双孔拱涵的浇筑技术,指出喀斯特地貌隧道施工中应对地质进行超前预报探测,从而确保施工人员及设备安全。%Combining the example for Maojia Tunnle Karst Cave,the paper has the survey of the factual circumstance of the karst cave,undertakes the treatment on the slurry weak foundation by adopting respective measures according to the conditions based on the previous ideas,indicates the high-pressure rotary grouting pile and the grouting technique of the double-hole arch culvert,and points out the advanced forecasting exploration should be taken in the karst tunnel construction,so as to ensure the safety of the construction personnel and the equipment.
