Abstract
As urban underground space development advances to deeper levels,ultra-deep foundation pit projects in soft soil areas face significant challenges in controlling retaining structure deformation and ground surface settlement.This study takes a metro station deep foundation pit in Hangzhou as a case study,addressing the soft soil foundation characteristics and constraints of nearby sensitive environments.A comprehensive support system,consisting of"underground continuous walls,servo steel supports,and bowl-shaped excavation,"is proposed.By integrating a real-time hydraulic-controlled servo steel support system with a staged stress release bowl-shaped excavation method,and utilizing a high-precision 3D monitoring network,the spatial-temporal evolution of the horizontal displacement of the retaining structure,support axial force,and surface settlement is systematically analyzed.The research demonstrates the synergistic effect of servo control technology and zoned excavation strategies,offering an innovative paradigm of"active control replacing passive reinforcement"for deep foundation pit engineering in soft soil areas.This approach holds significant practical value for the development of underground spaces in urban dense areas.关键词
