摘要
将盾构法施工隧道开挖引起的地表下沉以及盾构挤压引起的地表隆起均视为随机过程,应用随机介质理论,对隧道施工所引起的纵向地层移动与变形进行了分析,推导了相应的计算公式。工程实例分析表明,该方法效果良好。
The settlement or heave of ground surface due to tunnel excavation or push of shield is considered as a stochastic process and the stochastic medium theory is applied to predict and analyze the movement and deformation of stratum in longitudinal section due to tunnel construction, and the corresponding calculating formulas are derived. An example of case history shows that the prediction method developed in this paper can obtain good results.
