目前关于爆破粉尘可视化的研究报道较少。在分析城市拆除爆破粉尘的基础上对高斯模型进行修正构建了改进型高斯扩散模型，采用 Matlab GUI 工具箱对所构建模型进行了可视化软件设计。软件可以用来计算粉尘源强，并能够精确绘制该粉尘源强条件下爆破粉尘浓度分布三维图及其二维图。采用 Matlab GUI 工具箱所绘制的二维和三维图形能够直观、形象的反应任意时间点任意坐标精度以及一定范围内的爆破工程粉尘的扩散状态。%Blasting dust visualization studies were reported few nowadays. Based on the analysis of the urban demolition blasting dust,the Gaussian dispersion model was obtained by modifying the Gaussian model,and the Mat-lab GUI toolkit was also used to build the model of the visualization software design. The software was used to calcu-late the dust source strength and the ability to accurately draw a three-dimensional diagram blasting dust concentra-tion distribution and two-dimensional graphics. The two-dimensional and three-dimensional graphics based on Matlab GUI toolbox could draw intuitive reaction image coordinates of any point accuracy at any time and spread state of the range of blasting dust.
