Abstract
With the advancement of urbanization,deep foundation pit projects in deep soft soil strata face significant challenges.This paper systematically reviews the deformation characteristics of such foundation pits and the impact of local support failure on their stability.Research indicates that stress release due to soil unloading,rheological properties,and the interaction between the support structure and the soil are the core mechanisms leading to deformation,primarily manifested as lateral displacement of the retaining structure,bottom heave,and surrounding settlement.Local support failure,influenced by geological,design,and construction factors,can exacerbate deformation and threaten overall stability,with its impact mechanism varying under different support structures and geological conditions.Current research shows deficiencies in the coupled effects of multiple factors,special working conditions,and methodological optimization.关键词
