摘　　要：滨海相软土地层灵敏度高,深基坑施工风险高。为保证深基坑安全快速施工,本文以津沽海河隧道盾构始发段深基坑为实例,利用数值模拟和现场监测手段揭示了滨海相软土深基坑围护结构的变形规律,探索了基于5G技术的自动化实时监测技术在深基坑施工监测中的应用。实践表明,模拟结果和实测数值误差维持在合理范围,相对比传统模式的监测,5G深基坑自动化实时监测技术更具综合、准确、智能、实时等优势。Sensitivity of soft soil layers in coastal areas is high,and the construction risk of deep foundation pits is high.To ensure the safe and rapid construction of deep foundation pits,this article takes the shield tunneling starting section of the Jingu Haihe Tunnel as an example.Numerical simulation and in-site monitoring are all adopted to reveal the deformation law of soft soil deep foundation pits in coastal areas.It explores the application of automatic real-time monitoring technology based on 5G technology in the construction monitoring of soft soil deep foundation pits.Engineering practice has shown that the errors between simulation results and actual monitoring are in a reasonable range.Compared to traditional monitoring modes,5G deep excavation automation real-time monitoring technology has more comprehensive,accurate,intelligent,and real-time advantages.
