挡土墙安全系数的抗震可靠性分析
Seismic reliability analysis of safety factor on retaining wall
【摘要】 从重力式挡土墙的滑移和倾覆稳定性出发,建立了考虑地震作用时挡土墙的滑移和倾覆的功能函数。利用可靠度理论对两种状态的抗震可靠性进行了分析,提供了具有相同可靠度指标时,两种破坏模式安全系数的参考取值。
【Abstract】 Based on the slippage stability and overturning stability of gravity retaining wall,the performance function of the slippage and overturning on retaining wall are established in seismic state.The reliability indexes of the two failure modes are calculated and the reference values of safety factor of two failure modes are provided as the same reliability index.
