土方工程施工扬尘空间扩散特征及抑尘措施分析

Analysis on Spatial Diffusion Characteristics and Dust Suppression Measures of Dust in Earthwork Construction

近年来,我国城市化进程迅猛发展,在城市化建设过程中,不可避免地会产生扬尘污染。项目管理人员由于对扬尘起源和扩散规律认识不到位,不能采取有效的应对措施降尘,进一步加剧了空气污染,为人们生活环境和身体健康带来巨大威胁。针对此问题,本文从工程实际出发,对土方施工过程中扬尘起源类型进行全面分析,并通过归类法探讨了不同起源类型扬尘的空间扩散特性,最后根据不同扬尘空间扩散特点,提出相应的抑尘措施,为城市土方工程施工扬尘治理提供参考。

In recent years,with the rapid development of urbanization in China,dust pollution will inevitably occur in the process of urbanization construction.Project managers can not take effective measures to reduce dust due to their poor understanding of the origin and diffusion of dust,which further aggravates air pollution and poses a great threat to people's living environment and health.In view of this problem,starting from the engineering practice,this paper comprehensively analyzed the source types of dust in the process of earthwork construction,and discussed the spatial diffusion characteristics of different types of dust by classification method.Finally,according to the spatial diffusion characteristics of different dust,corresponding dust suppression measures are proposed,which provides reference for dust control in urban earthwork construction.
