以渡槽槽架结构的层间位移和顶点位移作为控制标准，提出了渡槽槽架结构在小震作用下位移控制的可靠度分析模型；基于现行相关规范，提出了渡槽槽架结构的层间位移和顶点位移控制限值；根据各随机变量的统计特征，采用Monte-Carlo模拟与有限元相结合的方法对渡槽槽架结构体系位移控制的可靠度进行了研究，为渡槽结构在地震作用下的可靠度分析和设计提供了一种新方法。

Taking inter-storey and peak displacements of an aqueduct frame structure as a control index, the reliability model of the aqueduct structure controlled by horizontal displacement subjected to a small earthquake was built. On the basis of the relative specifications, the limit values of inter-storey and peak displacements were put forward. According to the statistical characteristics of design parameters, the reliability controlled by displacement of the aqueduct structure system under a small earthquake has been studied using the method combining Monte Carlo simulation with finite element. A new reliability analysis and design method of aqueduct structure under earthquake action was put forward.
