摘要:
为研究地铁深基坑各因素之间的动态联系，提高地下工程施工风险评估准确性，提出改进熵权-DEMATEL-ISM（决策实验室法与解释结构模型）动态风险评估模型。以广州某地铁深基坑为例，将改进熵权-DEMATEL结合计算风险评价指标的组合权重以识取关键驱动因素，基于DEMATEL-ISM法对影响因子进行层级划分，综合分析各风险指标间关联性。最后经模糊综合评价计算隶属度函数和综合评价值。研究结果表明：深基坑施工过程中最关键影响因素为施工质量管理，综合施工风险等级为Ⅱ级，结果与实际情况相符，验证该方法的有效性。研究结果可为富水软土深基坑施工风险分析提供参考。
Abstract:
In order to study the dynamic relationship among various factors in deep foundation pit of subway,thus improve the accuracy of risk assessment on underground engineering construction,an improved entropy weight-DEMATEL-ISM （decision making trial and evaluation laboratory-interpretive structural modeling method） dynamic risk assessment model was proposed.Taking the deep foundation pit of a subway in Guangzhou as an example,the improved entropy weight and DEMATEL was combined to calculate the combined weight of risk assessment indexes to identify key driving factors.Based on the DEMATEL-ISM method,the influencing factors were hierarchically divided,and the correlation among various risk indexes was comprehensively analyzed.Finally,the membership function and comprehensive evaluation value were calculated through fuzzy comprehensive evaluation.The results show that the most critical influencing factor in the construction process of deep foundation pit is the construction quality management,and the comprehensive construction risk level is level II.The results are consistent with the actual situation,which verifies the effectiveness of the method.The research results can provide reference for risk analysis of deep foundation pit construction in water-rich soft soil.
