摘要
为了科学、合理地获得采空区建筑地基稳定性等级,避免残余变形对地基稳定性的影响,提出了基于博弈论组合赋权和灰云模型理论的建筑地基稳定性评价模型。首先,根据已有研究选取了7个评价指标建立地基稳定性指标体系;其次,分别采用层次分析法、改进的标准间重要性相关性(CRITIC)法确定评价指标的主观权重和客观权重,并依据博弈论进行组合赋权,避免了人为因素对权重确定的影响;最后采用灰云模型理论确定建筑地基的稳定性等级,实现了定性与定量之间的转换。将研究成果应用于工程实例中,为采空区建筑地基稳定性的评价提供了一种新方法。
In order to obtain the stability grade of building foundation in goaf scientifically and reasonably and avoid the influence of residual deformation on the stability of building foundation,an evaluation model of building foundation stability was proposed based on the combination weighting of game theory and grey cloud model theory.Firstly,seven evaluation indexes were selected to establish the foundation stability index system according to the existing research.Secondly,the analytic hierarchy process and improved criteria importance though intercrieria correlation(CRITIC)method were used to determine the subjective weight and objective weight of the evaluation index,and the combined weight was given according to the game theory to avoid the influence of human factors on the weight determination.Finally,the grey cloud model theory was used to determine the stability grade of building foundation,and the transformation between qualitative and quantitative was realized.The research results were applied to engineering examples and a new method was provided for evaluating the stability of building foundation in goaf.
