摘　　要：为了更好地了解桥梁在不同荷载等级状态下的极限状态,通过运用改进的一次二阶矩计算方法进行桥梁挠度的可靠度模拟分析,并通过利用大型有限元AD INA软件进行模拟实验,以模拟所得的数据进行可靠性评估计算,为桥梁挠度的可靠性评估提供新思路和方法。So as to master better the limiting condition of bridge in bearing capacity under action of different grade of load, the paper analyses the simulation of bridge deflection reliability by numerical procedures of first moment of second order, conducts as well the simulation experiment with large - scale finite element software ADINA, and carries out yet calculatiom of reliability assessment using the obtained data, which provide a new thought and methods for reliability assessment of bridge deflection.
