Reducing Construction Dust Pollution by Planning Construction Site Layout

Many construction activities generate fine particles and severely threaten the physical health of workers. Although many dust control measures are implemented in industry, occupational risks still exist. In order to improve level, this study proposes a new method reducing pollution through reasonable site layout plan. This is based on field measurement diffusion law. The law can be fitted monitoring data. With law, average concentration exposed workers different layouts simulated. addition, cost concern for managers. Therefore, total transportation reduction another optimization objective. Finally, multi-objective particle swarm (MOPSO) algorithm used search an optimized that reduce simultaneously. result shows significantly reduced by 60.62% 44.3%, respectively. paper quantifies provides managers with practical solution at low cost.
