山区高速公路施工与既有道路保通技术研究

Research on Expressway Construction in Mountainous Area and Existing Road Maintenance Technology

高速公路施工是我国重要的交通组成部分,对改善民生、经济发展等各项领域具有重要的战略意义。近年来高速公路施工项目发展迅速,因此施工过程中与现有道路保通的交叉干扰不可避免,针对山区高速公路施工与既有道路保通的影响与经济价值进行分析。根据现场实际交通量的情况,对保通方案进行合理布置,对防护棚进行专项设计,确保快速施工,减少既有道路的交通压力。保通过程中选择合理的导行方案,以及进行适当的交通管制,确保行车行人的安全。

Expressway construction is an important traffic component of our country,and has important strategic significance for improving people's livelihood,economic development and other fields.In recent years,expressway construction projects have developed rapidly,so the cross-interference between expressway construction and existing roads is unavoidable.The impact and economic value of expressway construction and existing roads in mountainous areas are analyzed.According to the actual traffic flow on site,the traffic protection scheme is reasonably arranged and the protective shed is specially designed to ensure rapid construction and reduce the traffic pressure of existing roads.To ensure the safety of pedestrians,it is necessary to select a reasonable guide plan and carry out proper traffic control during the journey.
