Study On Green Design Of South Section Of Xi’an Outer Ring Expressway

With Chinese construction industry prospering in recent years,various constructions including bridges,highways and tunnel engineering are being built across the whole country.Due to urgent market demand needs,coupled with the urgent needs of the national economic development,more and more construction project have been approved and more and more money are invested into infrastructure construction.At the same time,the field of traffic construction is a resource consuming industry,plenty of resources were wasted,causing serious damage to ecological environment.Under this circumstance,more and more people are thinking: how to make environmental protection and economic development coexist harmoniously? In the process of thinking,there is the idea of "green traffic design".The so-called green traffic design,is in the traffic engineering design,under the premise of ensuring the basic requirements of quality,safety etc.,through the design and the reasonable technical progress,to maximize resource conservation and construction activities to reduce the negative effect to the environment,to achieve a green four sections(energy saving,land saving,water saving,material saving and environmental protection).The essence of green design is a method to save resources and protect the environment,is put forward to the construction of the project more stringent norms,is the realization of human and environment,human and society,human and economic effective unification.This paper discusses and studies the actual situation mainly through the green design technology of Xi’an outer ring expressway southern section,detailed investigation by topography and meteorological and hydrological and geographical environment of the actual field,the characteristics of the project are analyzed,and the main influence factors on the traffic design of the road.Then it summarizes and improves the design outline of the project,summarizes its design guiding ideology,design content and basic requirements,as well as the overall design principles.Finally,in order to meet the design outline,research and analysis of green design for the southern section of Xi’an outer ring expressway traffic,specifically from the route design,pavement design,traffic engineering and landscape environmental protection and other aspects of design.The content of this paper is to improve people’s awareness of environmental protection and improve energy efficiency,and provide a reference for the future design of green transportation.
