| 摘 要： | 高等级道路桥头引道工后沉降是道路养护中所面临的主要问题.长期以来,养护部门一直缺乏明确的评价与养护标准,为此结合上海市管公路的养护实践,通过理论分析和现场试验,提出了高等级道路桥头引道不均匀沉降的判定指标,并给出了相应的评价标准和养护标准,成果与实际情况具有良好的相关性,可操作性强,已经纳入了《公路沥青路面养护技术规范》(JTJ 073.2-2001).

| Abstract: | In order to provide the explicit and rational standards for settlement treating at bridge approaching section, the relations between subjective feeling on the vehicle and differential settlement are discussed in this paper. By field subjective evaluating testing on various settlement instances and theoretical analysis, the faulting value and differential gradient are educed as evaluating index for settlement treating and the corresponding standards are provided for maintenance guidance. It is proved that the standards are fit for maintenance practice in roads of Shanghai. |
