摘　　要：阳洞滩2号隧道为双洞单向交通隧道。隧道施工过程中出现了隧道塌方。借助数值分析技术,结合数值模拟,仿真分析隧道塌方抢险的力学效应,进而形成阳洞滩2号隧道右洞YK194+040-YK194+085段处理方案。为隧道的安全施工提供了技术保障。Yang Dong Tan No. 2 tunnel is for two hole one-way traffic tunnels. The tunnel collapse happen during its construction. By using the numerical analysis technology, combined with numerical simulation, the simulation analysis of mechanical effect of tunnel collapse rescue is made in this paper. Later the positive hole beach No. 2 tunnel right hole YKI94 ＋ 040 - YK194 ＋ 085 segment processing scheme is formed . It will provide the technical support for the construction safety of tunnel.
