Study On Expressway Landscape Application Based On BIM Technology

With the rapid development of social economy,travel is no longer to meet the transfer of the location,but to meet the safety and convenience while a beautiful and comfortable driving environment.A good landscape design can not only improve the driving environment,But also ease the driver's visual fatigue and improve the safety of traffic,In the virtual space,the scientific and rational landscape design and make the road construction negatively impact on the environment to the lowest as much as possible,which can maximally the display the beautiful dynamic landscape,It can achieve the organic integration of expressway landscape and terrain environment.This paper is based on the BIM technique which studies the expressway road landscape design,and points out the concept of the driver's visual partition according to the dynamic visual characteristics.The technology of PowerCivil software is used to analyze the design method of road plane,longitudinal section,cross section and ancillary structure.Combined with the terrain to build a virtual space,The characteristics of different landscape partitions are used to study the methods of landscape design,and BIM technology is used to realize the dynamic experience of landscape in the virtual space.Through the Lumenrt landscape simulation software,the highway landscape simulation model was established,and the landscape plan were investigated and evaluated.The survey results are combined to analyze the He Huiguan expressway.This further validates the feasibility of BIM technology in highway landscape application.This paper puts forward the application of BIM technology in landscape design,which not only creates a safe and comfortable road landscape,but also improves the efficiency of landscape design and expands the application scope of BIM technology.
