隧道施工人员安全风险双网耦合模型设计及应用
Design and application of a dual-coupling network model for safety risk relationship of tunnel construction worker
摘要
Abstract
As the primary executors of construction activities,construction workers have a risk-sharing relationship due to cooperation in activities,and a risk transmission relationship due to process connections.However,there has not yet been an effective or reasonable way to study the risk relationship between construction workers.Therefore,this article introduced the principle of dual network coupling and utilizes social network analysis(SNA)to develop a model that visualizes the safety risk relationships among tunnel construction workers.This model offered a fresh perspective for studying tunnel construction safety risks and serves as a new tool for preventing the occurrence of safety loss.The model first identifies construction safety risk factors(CSRFs)using the WBS-RBS method,which determined the coupling relationship between construction activities and CSRFs.The set of construction workers was determined using the OBS-WBS method,and it determined the coupling relationship between construction workers and construction activities.The construction schedule network plan was utilized to clarify the interactive relationships among construction activities.Subsequently,based on the coupling relationships among construction workers,construction activities,and CSRFs,the construction activity network is transformed into a construction workers'risk relationship network through social network analysis(SNA).The role positioning of construction workers was further explored through centrality degree analysis.Finally,the model was applied to the Mizhou Tunnel in Guangdong as a case study to analyze the risk relationships among construction workers and determine their role positioning.The results indicate that different construction personnel occupy distinct roles within the risk relationship network.Construction project managers assume the role of influencers,construction site managers act as intermediaries in risk transmission,and construction site operators are primarily affected parties.The results can enable construction managers to gain a deeper understanding of the role positioning and task allocation of various personnel in safety management.As a result,targeted safety control suggestions can be proposed to enhance personnel safety management efficiency.关键词
