摘要
功能性道路是道路设施的发展目标和方向,也是新一代交通运输系统的重要组成部分。但现有的道路设计方法多基于路面结构的结构承载能力和车辆行驶的通达性要求,对于功能性道路并不完全适用。对此,首先分析了功能性道路的内涵,指出了功能性道路的四个主要构成,包括安全提升型道路、智能服务型道路、绿色环保型道路、自主适应型道路。随后基于现有道路设施的设计内容、方法和手段,探讨了新一代功能性道路在设计过程中的关键点、设计框架以及技术应用,并指出:BIM技术、GIS技术、有限元分析技术和拓扑优化技术可有效支撑功能性道路中新材料、新结构、新构件的协同设计,将成为新一代功能性道路设计方法的发展趋势。
Functional road is the evolution direction of the new-generation road infrastructures.It also plays an important role in the transportation system.Existing road design methods are based on the structural bearing capacity and the demands of ride quality,which is not applicable for the functional road.To study the new design method of the functional road,the contents of the functional road are determined,including the safety-improve road,the intelligent road,the green road and the self-adaptive road.Based on the current road design contents and methods,the key points,design frameworks and design techniques are discussed.It is pointed out that the Building Information Modeling(BIM)technique,the Geographic Information System(GIS)technique,the finite element analysis(FEA)technique and the topology optimization method can effectively support the design of the new materials,structures and elements in the functional road,and therefore boost the development of the functional road.
