基于集对可拓粗糙集方法的高边坡爆破施工安全风险评价
Safety risk assessment of high slope blasting construction based on set pair-extension analysis
摘要
Abstract
Considering that the high slope of highway rock cut by blasting excavation is easy to cause the decline of slope stability and the vibration caused by blasting damage to nearby structures,personnel casualties and other security risks,6 factors,i.e.slope height,slope shape and slope ratio,geological condition,blasting design scheme,blasting area environment,safety supervision and management were used to determine the classical domain and joint domain of the proposed evaluation sample,membership function was constructed based on identity-discrepancy-contrary analysis,and a security risk assessment model was established based on set pair-extension analysis method and rough set theory to calculate the safety risk evaluation index weights and evaluate the safety risk of high slope blasting construction.The results show that high slope blasting construction safety risk assessment level is moderate risk,which is consistent with the field survey results.The evaluation method can truly reflect the uncertainty of high slope blasting construction safety risk assessment process,and improve the safety risk assessment accuracy of the high slope blasting construction.The evaluation model analysis is simple,and can provide risk prediction for high slope blasting construction,effectively reduce the probability of safety accidents and save the cost of construction safety.关键词
