摘要
为降低施工过程中的安全隐患,提高施工现场安全评价的有效性,通过对影响施工安全的因素进行归纳分析,建立了施工安全评价体系,并基于物元可拓理论及熵权理论建立了熵权-物元可拓模型.通过计算评价指标与评价等级之间的关联度,结合熵权法确定指标权重,最终得到施工安全评价等级的综合关联度,对施工现场的安全性进行定量评价,以两个在建项目为例,验证了该模型的有效性和可行性.结果表明:基于熵权-物元可拓的施工安全评价模型是熵权理论和物元可拓理论的有机结合,可以有效地对施工安全状况进行定量评价.
Abstract
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.
