STYDY OF THE DYNAMICS OF THE AIRFLOW DURNING EXCAVATION WORKS IN ZONES ANTHROPOGENOUS BUILDING
It is shown that the excavation affect the degree of dust urban environment is particularly important process of reducing dust emissions in the areas of residential buildings, the concentration of public buildings, playgrounds, parks. Researches selection of fine silt dust in the areas of development of fine-grained soil that 70 % involved during excavation in Volgograd. Performed a comprehensive study of the physico-chemical processes in the atmospheric boundary layer during excavation, built on natural and computational experiments. On a laboratory wind tunnel revealed that the nature of dust dispersed in the development of arrays depends on climatic conditions, in particular, wind speed and physico-mechanical properties of rocks. The specialized GIS application that allows you to simulate the dynamics of air flow in areas with anthropogenic buildings, which is based on the methods of mathematical modeling and simulation, visualization techniques and building surfaces, methods for developing software applications.
