【摘要】 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。更多还原

【Abstract】 During the construction of shield tunnel, the ground around the shield has been changing all the time. Based on the previous predicting models of ground movement, a set of computer system has been established to predict and simulate the ground deformation in shield tunneling with the aid of the 2D and 3D space graphic simulation technology.更多还原
