根据实测数据，以多车道公路桥梁车辆荷载效应组合为背景，基于ＩＳＯ２３９４提出的原则，探讨了荷载效应组合系数的统计方法，以合理确定参与组合的各种荷载的设计值．
According to the measured data, based on the combination of vehicle load effect of multi-lane road and bridge, based on the principle proposed by ISO2394, the statistical method of load combination coefficient is discussed in order to reasonably determine the design values of various loads involved in the combination.
