Tunnel construction dust monitoring and dust control technology of high altitude and high and cold area

摘要

In order to improve the high altitude harsh construction environment, study tunnel construction dust concentration and distribution law of different construction section, using the membrane filter dust method to achieve the dust concentration of different section, using the statistical to analysis the origin and distribution law, putting forward different dust control measures for different construction stages, to improve the high altitude tunnel construction environment. The results of dust prevention and control of high altitude region are of great significance.
