摘　　要：文章提出一种大型建筑群施工阶段扬尘排放量估算方法,该方法首先将参照点设置在被排放源的上风向,避免受到污染扩散影响,再以排放源作为圆心布点,下风向设置监测点。接着通过概率统计的现场实测数据来对扬尘颗粒阻力计算,在大量的实际测量基础上获取扬尘排放源所排放量的长期平均水平,最后将建筑扬尘排放源分成建筑施工以及拆除两大类,分别计算排放因子,文章方法能够有效的对扬尘排放量估算,与传统方法对比,文章方法所估算的数据更加接近实际数据。This paper proposes a method of estimating fugitive dust emission in the construction stage of large building complex.Firstly,the reference point is set in the upwind direction of the emission source to avoid the influence of pollution diffusion,and the monitoring point is set in the downwind direction with the emission source as the center.Then,the resistance of dust particles is calculated based on the field measured data of probability statistics,and the long-term average level of the emission of dust emission sources is obtained based on a large number of actual measurements.Finally,the construction dust emission sources are divided into two categories:construction and demolition,and the emission factors are calculated respectively,so as to complete the estimation of dust emission.Experiments show that this method can effectively estimate the dust emission.Compared with the traditional method,the data estimated by this method is more close to the actual data.
