基于组合赋权-SPA的改扩建高路堑施工安全风险评估
Safety risk assessment of rehabilitation and expansion slope construction based on combined empowerment-SPA
摘要
Abstract
To scientifically assess the safety risks during the construction of renovated and expanded cutting high slopes,this paper proposes a comprehensive evaluation method based on combined weigh-ting and set pair analysis(CW-SPA).This study first establishes a targeted evaluation system compri-sing 6 primary indicators and 14 secondary indicators.This system is built upon existing industry guidelines while critically incorporating the distinctive features of expansion projects,namely"uninter-rupted traffic flow"and"secondary excavation."It thus encompasses key risk factors such as slope widening methods,excavation height,and traffic load capacity.The CW-SPA model synthesizes subjective and objective weights to determine indicator significance and computes their connection degrees with predefined risk grades.A case study reveals a critical divergence:the model assesses the risk as high,contrasting with the moderate risk identified by conventional guidelines.This discrepancy substantiates the model's superior relevance and reliability in capturing risks inherent to reconstruction and expansion scenarios.Furthermore,a sensitivity analysis pinpoints slope excavation height,ground-water conditions,rainfall intensity,and the expansion method as the pivotal influencing factors for the project.These findings provide crucial insights for optimizing construction plans and implementing effective risk control measures.关键词
