Reach Of Diffusion Model Of Liner Dust Source In Demolition Blasting Engineering In The City

Recently, fog and haze appears frequently, and it has become the focus of the society. There are many causes of haze, and one of the reason is the Influence of construction dust in the construction of the new urban and reconstruction of old city. And demolition is an indispensable part. Demolition blasting is the one of the most commonly used methods in demolition large buildings. However, it will produce a lot of dust. We should study the dust diffusion model of city demolition blasting engineering, It will be helpful to choose the right pollution-prevention measures, to control blasting dust pollution, to protect the city atmospheric environment.The paper mainly study the blasting dust in blasting of large liner buildings. And it mainly analyzes in following four aspects. Firstly, access to information, and use the idea of mathematical modeling, to construct the diffusion model. Second, according to Zhuanyang viaduct demolition blasting engineering and Wang Jiazui overpass demolition blasting engineering in Wuhan, to do the characteristic experiment, and analyze the results. Third, Validate the model. Lastly, Use GUI-toolbox of matlab, to design the visual software of the model. It is the basis of blasting dust pollution prevention and control.By model construction, characteristic experiments, model validation and model visualization, there are following conclusion.(1) construct and validate the diffusion model of liner dust source in demolition blasting engineering in the city, and the specific formula is:(2) Use matlab GUI toolkit, program visualization software of line of diffusion model of liner dust source in demolition blasting engineering in the city, which makes the model more intuitive.Diffusion model of liner dust source in demolition blasting engineering in the city can be used in predicting blasting dust of liner building. And it is the basis ofblasting dust pollution prevention and control.
