四渡河特大悬索桥是一座主跨为900m的单跨悬索桥,宜昌岸采用隧道式锚,介绍隧道锚固系统数值分析过程中初始地应力场的形成,隧道式锚碇与公路隧道的新奥法施工过程模拟,隧道锚隧洞周边接触软弱层的模拟,简要分析了围岩的稳定性,得出隧道锚固系统的整体安全度。
The Siduhe Suspension Bridge is a single-span suspension bridge with a main span of 900m. Tunnel anchors are used in Yichang bank to introduce the formation of initial geostress field during the numerical analysis of the tunnel anchoring system. The construction of tunnel-type anchorage and road tunnel with new Austrian law Simulation of tunnel tunnel near the tunnel contact with the weak layer simulation, a brief analysis of the stability of the surrounding rock, tunnel anchorage system obtained overall security.
