大流量高速公路集中养护示范工程实施方案探讨

Research on the Implementation Plan of the Demonstration Project of Centralized Maintenance of Large Flow Highway

针对传统养护方式长时间的拥堵对路网服务能力影响较大,“集中养护”通过“远端诱导分流,近端强制分流”,实现全省路网总体可控,解决了养护作业引起的交通拥堵,减少了车辆通行与养护作业之间的矛盾。对广靖锡澄大流量高速公路,周边路网交通组织复杂、养护工艺流程和施工机械交叉、养护工期容许时间紧、不间断施工的特点,首先对周边路网交通流量预测分析,其次针对施工组织和施工工艺进行优化分析。研究成果对大流量高速公路集中养护有一定的借鉴作用。

In view of the long-term congestion of traditional maintenance methods,the service capacity of the road network is greatly affected."Centralized maintenance"achieves overall control of the province's road network through"remote induced shunting and near-end forced shunting"and solves the traffic caused by maintenance operations.Congestion reduces the contradiction between vehicle traffic and maintenance operations.This paper aims at the characteristics of Guangjing Xicheng high-flow expressway,the complicated traffic organization of the surrounding road network,the crossing of the maintenance process and construction machinery,the tight time of the maintenance period,and the uninterrupted construction.First,the traffic flow forecast analysis of the surrounding road network is followed by the second Optimization analysis of construction organization and construction technology.The research results have a certain reference for the centralized maintenance of large-flow highways.
