摘要
Abstract
During the excavation of deep foundation pit,the soil and supporting structure are disturbed,leading to deformation and structural damage of the foundation pit.Based on a finite element numerical analysis model of a deep foundation pit with row piles and inner bracing,the deformation and failure characteristics of the retaining structure are analyzed.The results indicate a gradual increase in the horizontal displacement and surface settlement of retaining piles.The influence of internal bracing on the deformation of deep foundation pit is significant,with the uplift at the bottom of the pit exhibiting arch-like deformation characteristics at both ends of the middle section.The arrangement of piles and internal braces effectively mitigates pit deformation,demonstrating a well-designed support scheme.关键词
