摘　　要：为降低建筑爆破对大气环境产生的污染,解决现有控制模型控制效果不佳的问题,构建大型露天建筑爆破粉尘污染控制优化模型。结合大型露天建筑的爆破方式,模拟爆破过程。综合考虑粉尘运动的三个阶段,建立爆破粉尘扩散运动方程,计算大型露天建筑爆破粉尘的产生量与控制量。最终在边界条件的约束下,从水雾捕尘和控制空间通风,实现大型露天建筑爆破粉尘的污染控制。现场测试结果表明:通过设计模型的应用,大型露天建筑爆破施工后的粉尘浓度能够维持为200 mg/m^(3)以下,且降尘效率高于预设值,即优化设计模型具有良好的粉尘污染控制效果。In order to reduce the pollution of building blasting to the atmospheric environment and solve the problem of poor control effect of existing control models,an optimization model for dust pollution control of large open-air building blasting is constructed.The blasting process is simulated by combining with the blasting mode of large open-air buildings.Considering the three stages of dust movement comprehensively,the equation of blasting dust diffusion movement is established to calculate the production and control amount of blasting dust in large open-air buildings.Finally,under the constraint of boundary conditions,the pollution control of blasting dust in large open-air buildings can be realized through water mist dust capture and controlled space ventilation.The field test results show that the dust concentration of large open-air buildings after blasting construction can be maintained at below 200 mg/m^(3)through the application of the design model.The dust reduction efficiency is higher than the preset value,that is,the optimized design model has good dust pollution control effect.
