| 摘 要： | 对于盾构隧道的设计和施工，解析方法预测地表沉降，具有使用简便、物理意义明确的特点。在Sagaseta提出的基于由地层损失引起的地表沉降理论基础上，结合工程实际情况，提出了模拟盾构推进过程的三维地层损失模式，并推导了相应的地表位移计算解析公式，对实际工程具有参考价值。

| Abstract: | Analytical prediction of tunneling-induced ground movements can be used as guidance during design and construction for its simplicity and definite meaning. Based on elastic deformation theory, a closed-form solution for surface movements due to ground loss, which is derived from supposed 3D tunneling approaching procedure according to real-time engineering conditions considering shield machine deviation, is proposed to predict three-dimensional surface movements in undrained soil. The results show good accordance with actual cases. |
