摘　　要：扬尘污染是城市建筑工地的典型污染类型,为了降低工地扬尘污染程度,研究城市建筑工地扬尘污染扩散特征分析及污染治理措施。综合考虑施工进程,计算扬尘排放量,考虑机械力、随机力、黏性力等,求解扬尘污染的初始作用力,结合扬尘污染影响因素,在Fick定律和湍流扩散理论下,实现工地扬尘污染扩散特性分析。根据污染扩散特征分析结果,提出污染治理措施。通过实验得出:与传统方法相比,优化设计方法的污染浓度扩散特征分析误差降低了0.13 g/m^(3),并且扬尘污染程度有所降低,由此证明优化设计方法具有更好的分析精度性能和污染治理效果。Dust pollution is a typical type of pollution in urban construction sites.In order to reduce the degree of dust pollution in construction sites,the diffusion characteristics and pollution control measures of dust pollution in urban construction sites are studied.The construction process is comprehensively considered,the dust emission is calculated,the mechanical force,random force and viscous force are considered.The initial force of dust pollution is solved,and the influence factors of dust pollution are combined to analyze the diffusion characteristics of site dust pollution under Fick's law and turbulent diffusion theory.According to the analysis results of pollution diffusion characteristics,the pollution control measures are put forward.The experimental results show that:compared with the traditional method,the analysis error of pollution concentration diffusion characteristics of the optimized design method is reduced by 0.13 g/m^(3).The degree of dust pollution is reduced,which proves that the optimized design method has better analysis accuracy performance and pollution control effect.
