Tunnel construction method based on karst cave and underground river environment
The invention discloses a tunnel construction method based on a karst cave and underground river environment. The tunnel construction method comprises the following steps that S1, a tunnel section A is excavated to communicate with a karst cave; S2, an underground river is diverted, so that the underground river does not flow through the karst cave; S3, the karst cave is backfilled until the karstcave is backfilled to a tunnel foundation surface; S4, the cave wall of the karst cave is protected, and a plurality of anchor cables are uniformly constructed on the cave wall; S5, the karst cave isfully filled, and the anchor cables are connected with a fully filled backfill body; S6, the backfill body is excavated to form a tunnel section B communicating with the tunnel section A; and S7, bridge-crossing construction is carried out on the tunnel section A and the tunnel section B, so that the load of a bridge is located at the tunnel section A at the two ends. The tunnel construction method has the advantages of being stable, reliable, high in safety and capable of preventing settlement.
一种基于溶洞暗河环境的隧道施工方法，包括以下步骤S1：将隧道A段开挖至连通溶洞；S2：对暗河进行改道，使暗河不流经溶洞；S3：对溶洞进行回填，直至回填至隧道基础面；S4：对溶洞洞壁进行防护处理，并在洞壁上均匀施作多根锚索；S5：对溶洞进行满填，并使锚索与满填后的回填体连接；S6：对回填体进行开挖形成与隧道A段连通的隧道B段；S7：在隧道A段和隧道B段进行跨桥施工，使桥梁的载荷位于两端的隧道A段。具有稳定可靠、安全性高、能防止沉降的优点。
