【摘要】 从人车路相互作用出发,建立了人车路系统振动方程和路桥过渡段路面不平整模型,并通过编制的RCBP程序分析了车辆行驶舒适性的影响因素,最后确定了基于行驶舒适性的路桥过渡段差异沉降控制标准。结果不仅可以用于路桥过渡段差异沉降控制标准的相关规范,也可用于一般路基差异沉降标准的制定,对桥头跳车问题的处治和路桥过渡段路面的养护维修提供了科学决策依据。更多还原

【Abstract】 This paper sets up people-vehicle-pavement vibration equations and road unevenness model of bridge-approach,and compiles RCBP program to analyze effect factors of vehicle ride comfort.At last,the author builds up differential settlement control criteria of bridge-approach on ride comfort.The results may be used as the specifications for the embankment differential settlement criterion,and provide the basis on solving bump and maintaining bridge-approach pavements.更多还原
