Research On Highway Construction Environment Protection Technology At Loess Plateau Area In Shanxi Province

The key highway construction in China has been changed from the flat in plain districtto mountain and hill terrain in resent years, leading the contradiction between mountainhighway construction and environmental protection becoming more and more serious. Asthe excavation and embankment filling in highway construction process will cause nativevegetation and animal habitat destruction, water and soil erosion, and a series of ecologicalenvironmental problems, how to prevent air pollution, water pollution, noise pollution, andconstruction operations from impacting on the environment is one of the important researchdirections of the road industry in the highway construction process. How to do a good job ofsoil and water conservation, and how to combine green technology and engineering diseasemanagement were the bigest problems in Shanxi Loess Plateau region highway constructionprocess. In this paper, according to Jing’an expressway construction projects, issues relatedto environmental protection in loess region highway construction process are keytechnology research.This paper did some research on the analysis of environmental protection relatedfactors in highway construction process. Then the reaearcher proposed a feasible controlmeasures to prevent air pollution, water pollution, noise pollution and construction wastepollution after analyzing the specific problems encountered in the physical works.Inallusion to soil slope and rocky slope stabilization techniques in loess areas,combined thecorresponding solutions with the highway green technology,formed sets of key technologiesof environmental protection for the northern Shanxi special geological, climatic and naturalfactors were also been studied in this paper.The research shows that environmental protection based on the characteristics ofgeography and complex terrain in the Loess Plateau in northern Shanxi expresswayconstruction should be used comprehensively in the highway construction,through thecombination of different technologies to compensate for their limitations in terms ofgovernance.Try to choose the greening local plants to adapt to the northern Shanxi droughtclimate, we must establish the awareness of environmental protection in highway designstage,select appropriate measures of environmental issues in the overall planning of highway construction.
