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