探析高速公路工程临时改道的设计

Analysis on Design for Temporary Diversion in Expressway Engineering

我国社会经济发展水平不断提高,公路交通建设需求也在不断加大,尤其是作为公路系统中重要组成的高速公路,其建设规模和数量要求均在不断提高。在高速公路工程建设当中,新建高速公路和原有高速公路难免出现交叉情况,如何有效处理两者间的关系,保证原有高速公路的通行安全,就需要对其进行改道设计和处理。本文首先阐述了高速公路工程临时改道设计的出发点,指出改道设计中应遵循的原则,进而就改道设计的规模和参数确定进行专门分析,最后提出了改道设计中的保通方案,以期为相关设计施工单位提供有效参考。

China＇s social and economic development level has constantly improved; the highway traffic construction requirements are also increasing. Especially expressway, as an important component of highway system, its construction scale and quantity requirements are constantly improved. In expressway engineering construction, the newly built expressways are inevitably to cross the original expressways. In order to effectively deal with the relationship, ensure the safety of the original highway traffic, diversion design of the new expressway is necessary. This article first expounds the starting point of temporary diversion design of the expressway engineering, points out the principle that the diversion design should follow, and analyzes the scale and parameter determination of diversion design, and finally proposes the traffic-keeping scheme, in order to provide effective reference for the related design and construction unit.
