复杂高大模板安全风险识别与评价研究OA

Complex and tall formwork engineering has become a high-risk part of construction due to its intricate construction environment,extremely demanding load conditions,and high technical requirements,which are prone to causing safety accidents such as scaffold collapses and personnel falls from heights.To accurately identify and quantify risks,a risk assessment model that integrates the Analytic Hierarchy Process(AHP)and the Graham-Kinney Method(LEC)is proposed to achieve precise risk identification and quantification.Taking the 2#main shaft tower project of Shougang Luannan Macheng Mining as an example,a risk index system is constructed from three aspects:construction plan,construction implementation,and on-site management.The AHP is used to determine the weight of each risk factor,and the LEC method is combined to quantify the risk level,ultimately achieving a comprehensive evaluation of risks.The research results show that this integrated model can effectively avoid the subjective defects of single evaluation methods,accurately identify key risk points such as scaffold height,material quality,and safety education,thus providing a scientific basis for formulating targeted safety control measures for complex and tall formwork engineering.This has extremely important practical significance for improving the level of engineering safety management.
