桥梁荷载效应统计参数的动态摄取方法

The Collectting Method of Statistics Parameters of Bridge Load Effect

为了获取桥梁远程监测信息中的荷载效应的分布及特征参数,通过统计推断的优度拟合检验方法得到某时段的荷载效应分布,然后建立不同时段的荷载效应最大值概率分布,最后计算荷载效应的统计参数。为桥梁远程监测系统及评价体系提供了有利的数据。

Load effect monitoring of bridge is random variable. Its distribution and distributed parameters are unknown. We obtain distribution of one time term load effect by the fitting of statistical methods ,and construct different term＇s maxium distribution of load effect ,at last calculate parameters of load effect distribution.
