本文先分析了盾构隧道施工引起的地面沉降规律和原因,介绍地面沉降的预测方法。然后结合某城市隧道施工过程的地面沉降监测数据进行分析,运用沉降槽分布模型拟合结果,并且运用数学函数给予表达。最后得出的研究结果可供对今后类似工程参考,确保在施工过程中隧道周边环境的安全。
This paper first analyzes the rules and causes of ground subsidence caused by shield tunnel construction and introduces the prediction method of land subsidence. Combined with the monitoring data of ground subsidence during the construction of a city tunnel, the results are fitted by using the sedimentation tank distribution model and expressed by the mathematical function. Finally, the research results are available for reference to similar projects in the future to ensure the safety of the surrounding environment of the tunnel during construction.
