摘要
为探究地铁隧道施工安全风险因素作用机制,科学预防施工安全事故,引入N-K模型演化分析地铁隧道施工安全风险耦合。在施工安全风险因素定义和耦合机制分析的基础上,根据耦合层次网络模型构建耦合交互场景,并按耦合数量进行组合分类;建立基于N-K模型的耦合效应度量模型,进行耦合信息交互、耦合效应量化计算;以我国近20年发生的231起地铁隧道施工典型事故为例,验证该模型的有效性和准确性。结果表明:安全事故的发生与风险耦合值成正比,耦合因素越多则风险值越大;人-管耦合风险值最大,管-环耦合风险值最小;主观因素与客观因素的耦合更易导致安全事故的发生。
In order to explore the mechanism of safety risk factors in subway tunnel construction and prevent construction safety accidents scientifically,the N-K model was introduced into the evolution coupling analysis of safety risk in subway tunnel construction.On the basis of the definition of construction safety risk factors and the analysis of the coupling mechanism,the coupling interaction scenarios were constructed according to the coupling hierarchical network model,and the combined classification was carried out according to the number of coupling.The coupling effect measurement model based on N-K model was established,and the coupling information multivariate interaction and coupling effect quantitative calculation were carried out.The validity and accuracy of the model were verified by taking 231 typical accidents of subway tunnel construction in China in recent 20 years as examples.The results show that safety accidents are directly proportional to the risk coupling value,and the more coupling factors,the greater the risk value.The coupling risk value of human and management is the highest,and the coupling risk value of management and environment is the lowest.The coupling of subjective and objective factors is more likely to lead to safety accidents.
