Study on Evaluation of Dust in Highway Construction on Qinghai-Tibet Plateau
Keywords:Highway construction, Dust concentration, Ambient humidity.
With the rapid development of our country's economy and acceleration of urbanization construction, the original road construction to relieve the traffic pressure on the basis of should be improved. Tibetan plateau is located in southwest borderland in our country, the area of about 2.4 million square kilometers, occupying 1/4 of our country's land area , improving the traffic condition and road construction of this region have vital significance. Based on the mathematical model of particle size distribution and dust volume under different air humidity and wind speed during road construction, this paper evaluated the influence of dust volume brought by strong wind environment during road construction on the Qinghai-Tibet Plateau on the environment along the road, aiming at controlling the possible adverse impact of the project construction on the ecological environment to the lowest extent.
