国内外现行道路养护管理规范中,多采用车辙深度(Rutting Depth,RD)作为车辙病害的评价指标。为考虑道路使用者的需求、从车辆行驶质量角度评价车辙深度控制标准,该文首先分别建立了路面车辙激励模型和车辆行驶质量评价模型;在此基础上,在MATLAB/Simulink环境下进行车辆-路面系统动力学仿真分析,求得系统各输出响应;然后依据ISO2631《人体承受全身振动的评价指南》,建议了保证车辆良好行驶质量的车辙深度控制标准。该文的研究为进一步科学合理的评价车辙状况奠定了基础,也为道路管理部门进行路面养护管理决策提供了参考。
Rutting Depth (RD) is mostly used as the evaluation index of rutting diseases in the current domestic and international road maintenance management codes. In order to consider the needs of road users and evaluate the criteria of rutting depth from the perspective of vehicle running quality, a model of rutting motivation and vehicle driving quality evaluation was established respectively. Based on this, a vehicle- Pavement system dynamics simulation analysis, the system output response obtained; and then based on ISO2631 “human body to withstand vibration evaluation guidelines”, recommended to ensure good vehicle ride quality rutting depth control standards. The research in this paper lays the foundation for further scientific and reasonable evaluation of rut conditions and also provides a reference for road management departments to make road maintenance management decisions.
