In order to accurately evaluate the construction safety of industrial plants and reduce the accident rate,this paper con-structs a construction safety risk evaluation index system for industrial plants from five aspects:construction safety personnel management,construction safety technology management,machinery and materials,and construction safety and environment management,establishes a risk assessment model of the combined weighting method-extensible cloud model,and verifies the ef-fectiveness and feasibility of the model through engineering examples.The results show that the analysis model based on the ex-tensible cloud model theory has strong applicability and can be used for the assessment and management of construction safety risks in industrial plants.
