摘　　要：重庆长江鹅公岩大桥东隧道锚将双索总荷载为 2 60 0 0 0kN锚固于中等风化的泥岩和砂岩互层岩体内 ,岩体力学参数选取的恰当与否对锚碇安全稳定性有着重要影响。本文介绍了重庆鹅公岩大桥东锚碇岩体力学参数的取值过程及可能的破坏模式。A total load of 260000kN of two cables of Egongyan Bridge across Yangtze River in Chongqing is imposed on east anchorage fixed in inter layered rock mass of medium weathered mudstone and sandstone. The proper selection of rock mechanical parameters will have important impact on the safety and stability of the anchorage. In this paper, the choice of rock mechanical parameters of east anchorage of Egongyan Bridge across Yangtze River in Chongqing and possible failure mode are introduced.
