在桥头跳车过程中，驾驶员受到来自道路条件、交通环境等因素突变的影响，从而引发生理心理上的负担，导致心率的急速变化。根据路桥过渡段的行车实验及数据采集，主要分析了桥头跳车中车速及桥头沉降差对人体心率的影响强度及其相关性。%The driver suffer from the mutations of the factors such as road conditions,traffic envi-ronment of vehicle bumping at bridge-head,which causes physical and mental burden and the rapid chan-ges in heart rate.According to the carriageway experiments at bridge abutment and the data acquisition, this study analyzes the impact strength of the human heart rate of the speed and settlement difference at bridge -head and their correlation.
