摘要
采用FLAC差分软件,应用弹塑性理论,对韩家岭大跨度公路隧道开挖进行了数值模拟,并对其稳定性进行分析,以保证隧道运行安全经济合理.所得计算结果和有关结论弥补了我国在大跨度隧道分析方面的空白,为隧道的设计及施工提供重要参考.
Based on the elasto-plastic theory, a numerical simulation on Excavation of Hanjialing large span road tunnel is conducted using the FLAC-2D software. And the stability is analyzed to ensure the safety and economic rationality of the tunnel operation. The calculation results and relevant conclusions can make up blankness of the analysis on large span tunnels, and offer the important reference for the design and construction of tunnel.
