| Abstract: | 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. |
