基于灰色聚类的大型城市综合体基坑施工安全风险评价

Safety Risk Assessment of Foundation Pit Construction in Large-scale Urban Complexes Based on Grey Clustering

为科学评价大型城市综合体基坑施工安全风险,降低基坑事故发生概率,文中通过文献分析,确定了5个一级指标和16个二级指标,利用序关系分析法确定一级指标以及相应二级指标权重,计算得出,一级指标中施工人员指标权重占比最高;并采用灰色聚类法建立了大型城市综合体基坑施工安全风险分析模型,验证表明,该模型在实际应用中具有可参考性。

In order to scientifically evaluate the safety risks of large-scale urban complex foundation pit construction,reduce the probability of foundation pit accidents,protect the safety of construction personnel's lives and property,and improve the emergency response ability in case of accidents,this article determined 5 primary indicators and 16 secondary indicators through literature analysis,and used the method of sequential relationship analysis to determine the weights of primary indicators and corresponding secondary indicators,Calculate the highest proportion of construction personnel indicators in the first level indicators,and establish a safety risk analysis model for large-scale urban complex foundation pit construction using grey clustering method.The verification shows that the model has reference value in practical applications.
