盾构法隧道施工过程中,盾构附近一定范围内的土体始终处于不断变化的状态之中。沉降预测仿真技术是在已建立的盾构法隧道地层移动理论预测模型的基础上,借助二维和三维空间图形仿真技术对不同工作条件下盾构施工引起的地层位移的变化进行预测仿真,此项技术在实际工程中获得了较好的应用效果。
In the process of shield tunneling, the soil within a certain range near the shield is always in a state of constant change. The settlement forecasting simulation technology predicts the change of formation displacement caused by shield construction under different working conditions by means of two-dimensional and three-dimensional space pattern simulation based on the established prediction model of shield tunneling theory. Item technology in the actual project has been a better application results.
