随着上海进入后世博时代,道路建设的重点逐渐从新建、改建过渡到对现有道路的养护、大中修。道路本身的破损程度不同,破坏原因也比较复杂,如何在道路养护、维修资金有限的情况下,因地制宜地提出合理的大中修设计方案,是每个道路设计者面临的问题。针对道路大中修工程设计的基本步骤、设计要点、需要注意的问题等方面进行了探讨。依托上海市S1迎宾大道外圈全线大修工程建设实践,阐述了城市快速路道路大修设计中的设计要点。
With Shanghai entering the post-Expo era, the focus of road construction has gradually shifted from new construction and renovation to the maintenance of the existing roads and the cultivation of large and medium-sized buildings. The damage degree of the road itself is different, the reason for the damage is also quite complex. How to put forward the reasonable medium and large-scale design plan according to the local conditions when the road maintenance and the maintenance fund are limited is the problem that every road designer faces. Aiming at the basic steps, design points and problems that need attention in the course design of major and minor courses of road repair, Relying on Shanghai Yingbin Avenue outside the outer ring overhaul project construction practice, elaborated the design of urban expressway overhaul design points.
