摘要
Abstract
Addressing the challenges of complex on-site environments,diverse risk factors,reliance on experience in traditional safety management,and the lack of a scientific basis for monitoring layout at concrete batching plants,this paper proposes a risk field zoning method based on a multi-risk index calculation model.A multi-dimensional risk factor system covering personnel activities,mechanical equipment,hazard distribution,and environmental conditions is constructed.By introducing spatial rasterization and a distance decay function,a continuous risk field model is established.The analytic hierarchy process(AHP)is used to determine the weights of each risk factor,and the comprehensive risk value of each grid cell is calculated.Combined with geographic information system(GIS)spatial interpolation technology,a visualized risk data base map is generated to achieve spatial zoning of risk levels within the construction area.The results show that this method effectively reveals the spatial distribution characteristics of risks,provides a quantitative basis for the layout of intelligent monitoring on construction sites,and enhances the refinement and intelligence level of safety management.The research findings can serve as underlying algorithmic support for city information modeling and intelligent construction,offering a data foundation for micro-scenario-based full-lifecycle safety supervision in smart cities.关键词
