Safety Assessment of Widening Embankment Construction Based on Fuzzy Object Element Analysis
In order to effectively control the construction risk of widening embankment high slope,this work proposed a construction safety assessment model based on fuzzy object element analysis.Firstly,for the engineering characteris-tics of widening embankment construction,a safety risk assessment index system including 4 first-level indicators(trig-gering factors,traffic organization,construction environment,construction design)and 11 second-level indicators(construction season,natural disaster impact,traffic volume,traffic control and guided change,construction surround-ing environment,deformation of the original slope,fill height,foundation treatment,reinforcement method,complete-ness of design data,construction machinery)is constructed.Secondly,hierarchical analysis and entropy weight meth-od(EWM)were used to calculate the weights of primary and secondary indicators respectively.Finally,a safety risk assessment model for widening embankment construction was constructed by using fuzzy object element analysis,and it was then applied to actual engineering examples to verify the effectiveness of the model through comparison.The results show that the model can effectively assess the overall safety risk of widening embankment high slope construction.
