摘要
为准确了解地铁车站深基坑施工安全状况,文章系统考虑人、设备、环境、管理以及工程等影响深基坑施工的安全因素,建立地铁车站深基坑施工安全评价指标体系。综合使用层次分析法和熵权法确定权重,建立安全性评判模型,评价施工安全等级;最后利用反馈回的数据对施工现场安全性进行评价,验证了模型的适用性和科学性,同时表明熵权法在一定的情况下也可用于单一评价对象的权重计算。
To understand the safety situation of deep foundation pit construction in metro station, the evaluation index system is established based on systematic considerations of safety factors, such as people, devices, environment, management and engineering factors. The weight of evaluation index is calculated by use of AHP and entropy method, then the safety evaluation model is established to determine the safety level of construction. Finally, the applicability and scientificity of the model are verified based on safety assessment of construction site. The results also show that entropy method can be used to calculate the weight of single evaluation object under certain circumstances.
