Evaluation of deep foundation pit stability in water-rich silty sand layers based on game theory combination weighting method
摘要
Abstract
To address the issue of imbalanced weights from subjective and objective weighting methods in eval-uation of deep foundation pits stability in water-rich silty sand layers,this study proposes a combination weigh-ting method based on game theory.The method integrates the Analytic Hierarchy Process(AHP),entropy weight,CRITIC,and Principal Component Analysis(PCA)to comprehensively consider numerical relativity,data information volume,volatility,and information condensation,thereby obtaining optimal combination weights.Grey relational analysis is employed to assess the relative stability of working faces in deep foundation pits,while cloud modeling determines stability levels.Applied to the"Heat Source Replacement"centralized heating project in Julu County,the results demonstrate that horizontal displacement at the pile top exerts the most significant influence on the stability of deep foundation pit excavation in water-rich silty sand.The model evaluation classifies the excavation state as"very stable",which aligns with field observations,thereby valida-ting the method's effectiveness in enhancing the reliability of deep foundation pit stability assessments.关键词
