Environmental Disturbance Analysis and Control in the Excavation of a Foundation Pit Near a Building Structure

This study focuses on the analysis and control of environmental disturbance resulting from the excavation of a foundation pit in proximity to an airport hotel. The research aims to investigate the impact of pit excavation on the hotel structure, surrounding ground, and the behavior of the pile support system. The settlement pattern indicates that the hotel structure experiences greater settlements on its southern side, near the excavation site. Moreover, the excavation of deeper layers leads to a noticeable rise in the ground level, with the bottom of the negative first floor exhibiting higher elevation compared to the negative ground floor. These observations highlight the need for careful consideration of excavation depth and unloading effects during construction. Furthermore, the study examines the displacement and deformation characteristics of enclosure piles. It demonstrates that the perimeter pile wall experiences convergence towards the excavation pit, particularly at the bottom and near the top of the piles.
