临港西岛金融中心深基坑支护监测与变形特性研究——基于前撑式抗压注浆钢管桩的应用实践

Key Points

• The study aims to analyze the deformation characteristics and monitoring practices of a deep excavation support system using pressure-injected steel pipe piles.
• Developed a comprehensive monitoring plan covering the excavation and surrounding environment.
• Monitored key indicators including support structure displacement, internal forces, and surface settlement.
• Utilized real-time data collection to assess the performance of the support technology.
• Maximum lateral displacement of the protective piles reached 34.5 mm.
• Maximum surface settlement recorded at 107.3 mm.
• All core monitoring indicators remained within safe limits.
