| 摘 要： | 以某大型地下工程的设计、施工、监测为实例背景,系统介绍了富水、充填型溶洞的处理方法。在超前地质预报工作的基础上,结构设计采用超前注浆堵水、初期格栅钢架喷砼网支护、二次现浇钢筋砼衬砌的复合式衬砌方案。掘进采用中隔墙法开挖,并设置泄水洞辅助减压,取得了较好的效果。

| Abstract: | Based on the detail design, construction and supervision of large underground structures, this paper systematically introduces a treatment method for karat caverns in surrounding rock massives with abundant water and soil fillings. In the structure design composite lining is adopted, including front pre-grouting, grid steel frame, primary shotcrete-bolting support and reinforcing concrete lining. During excavation weep holes are designed so as to reduce water pressure. The project shows the design and treatment method for karat caverns is safe and reasonable. |
