广锡高速和江阴大桥集中养护工程交通组织探讨

Discussion on Traffic Organization of Intensive Maintenance Project of Guangxi High-speed Jiangyin Bridge

为缓解高速公路逐渐向大流量发展的背景下传统养护模式难以同时保障安全、畅通和养护质量的问题,探索集中养护新模式实践的可行性很有必要。依托广锡高速、江阴大桥集中养护工程,首先,根据项目路段调研资料,提出了三种养护方案;其次,分别从交通影响、工期、工效、施工质量和交通安全五个方面展开对比分析,凸显了集中养护的优势;最后通过实践工程,从交通影响和经济效益两方面验证了集中养护在一定范围内更适应大流量下的高速公路养护工作,成效可观。

In order to alleviate the problem that the traditional maintenance mode is difficult to guarantee safety,unblocked and maintenance quality at the same time under the background of the gradual development of expressway to large flow,it is especially necessary to explore the feasibility of the practice of centralized maintenance of the new mode.Relying on the intensive maintenance project of Guangxi high-speed Jiangyin bridge,firstly,three kinds of maintenance plans are put forward according to the investigation data of project sections.Secondly,a comparative analysis is carried out from the aspects of traffic impact,time limit,work efficiency,construction quality and traffic safety,highlighting the advantages of centralized maintenance.Finally,through practical engineering,the paper verifies the highway maintenance work which is more suitable for large traffic flow in a certain range from two aspects of traffic impact and economic benefit,and makes remarkable achievements.
