Analysis of the Impact of Shield Tunneling on Existing Shallow-Foundation Buildings:Considering Horizontal Distance and Burial Depth Factors
摘要
Abstract
To investigate the deformation influence of metro shield tunneling on adjacent shallow-foundation buildings,this study is based on a typical shield tunneling project in Beijing.A three-dimensional coupled model of the shield tunnel,soil,and shallow-foundation building was established using the FLAC3D numerical simulation software.The settlement and deformation characteristics of the building under different horizontal distances and burial depths were analyzed.The results indicate that the settlement and deformation of the building increase as the horizontal distance between the tunnel and the building decreases.When the tunnel burial depth increases from 23 m to 29 m,the range of ground disturbance expands,leading to an increase in both the overall settlement and horizontal deformation of the building.The building foundation constrains the shape of the surface settlement trough,resulting in a"U"-shaped settlement distribution when the tunnel passes beneath.The study reveals the deformation behavior and spatial effects of buildings induced by shield tunneling,providing a reference for risk assessment and control in similar urban metro projects.关键词
