Tianbao Highway Pollutants To Forecast Simulation Analysis On The Influence Of Road Environment And The Environment

Through environmental target monitoring of TianBao highway operation period,and the comparison of expected highway environmental project monitoring, dovalidation and summary, to determine the highway expected standard meets theenvironmental protection project monitoring, the main environmental benefits areachieved, by contrast, summarizes the lessons and experiences of highwayenvironmental protection, and puts forward countermeasures and measures forhighway environmental protection project, thus realize the sustainability of thehighway environmental protection projects. At the same time, this article through toTianBao highway environmental monitoring project data analysis, sorting, forTianBao high-speed environmental monitoring project put forward reasonablesuggestions and countermeasures, for the future of highway has some guidingsignificance to environmental protection. Finally, through the environment impactassessment results for the highway operation management puts forward relatedscientific data basis, which can also be for the environment along the highwaysustainable development, which provides the basis for environmental planning.In this article, through analysis of TianBao high-speed air monitoring data, on theeast branch of village, TianBao high-speed BaiHua forest farms, MaiJiShan andMaiJiShan tunnel entrance tunnel when the daily mean value in ambient airmonitoring and average monitoring, respectively for sulfur dioxide and carbondioxide in the atmosphere, the total suspended particulate matter, pm10concentrationmonitoring, and the results are list, using the method of atmospheric environmentalimpact assessment: through the evaluation method for the evaluation index. Based onthe model, line source forecast for TianBao highway, infinite line source model isadopted. Line source model is used to predict flow sources and other linear pollutionsources of atmospheric environment quality. Current source mainly refers to the motorvehicle through a road or street; Line source can be divided into limited long-termsource and the infinite long term source. For TianBao concentration of NO2in thefreeway around300m.Second, through to the TianShui section of WeiHe river water qualitymonitoring analysis, the evaluation method is: the river section water quality classification assessment using the single factor evaluation method, based on the crosssection of the indicators in the evaluation of the highest category a. Descriptionsection category, water quality conforms to or worse than words. For river monitoringsection is less than5, the concentration of all cross section of each evaluation indexcalculated arithmetic mean, and then evaluation method to evaluate the water qualityin accordance with the river section type of water quality and water quality conditionof each section. Water quality prediction model is adopted one-dimensional model.Finally for TianBao high-speed near19noise sensitive noise monitoring data tomonitor the analysis, we can through the acoustic environmental quality standard(GB3096-2008) and the environmental impact assessment technical guideline soundenvironment evaluation and monitoring (HJ2.4-2009), which mainly studies themodel and the relationship between the traffic noise, and the number of cars for theeffects of traffic noise, etc.issued by the ministry of communications for noiseprediction is adopted specification formally text code for the highway constructionproject environmental impact assessment (JTG B03-2006) is still using the newtechnology guideline FHWA model, but is simplified. For convenience of application,the new technical guidance to the mode of fixed quantity and attenuation values ormade further clear calculation method.At the end of the paper through road atmosphere, surface water and noisepollution result analysis, provide the corresponding environmental pollutionimprovement countermeasures and suggestions.
