Study on the Evaluation of Construction Safety Based on Entropy-Weight and Matter-Element Modeling
In order to reduce the safety hazards in the construction process and improve the effectiveness of construction site safety evaluation,this study establishes a construction safety evaluation system by summarizing and analyzing the factors affecting construction safety,and an entropy-matter-element extension model based on matter-element extension theory and entropy weight theory.By calculating the correlation between the evaluation indexes and the evaluation level,and combining the entropy weight method to determine the weight of the indexes,the comprehensive correlation of the construction safety evaluation level is finally obtained,and the safety of the construction site is quantitatively evaluated.Lastly,the validity and feasibility of the model are verified by taking two projects under construction as examples.The final research results show that our construction safety evaluation model is an organic combination of entropy-weight theory and matter-element extension theory,which can effectively evaluate construction safety status quantitatively.
