In-Situ Monitoring and Numerical Analysis of Deformation in Deep Foundation Pit Support: A Case Study in Taizhou

With the increasing prevalence of deep foundation pit projects in modern urban construction, deformation control associated support structures is crucial to ensuring construction safety. Despite growing importance this issue, research on excavation soft soil areas near sea limited. This study investigates characteristics and impact a geometrically complex project Taizhou, utilizing both long-term in-situ monitoring numerical simulation. The results indicated that maximum horizontal displacement was approximately within depth range 5 m, with value 34.5 mm. settlement top surrounding were determined be less than 25 mm, confirming safety process. process simulated analyzed by Midas GTS finite element software. showed similar variation pattern measured results, but generally lower values. provides valuable insights into serves as reference for future conditions.
