摘要
基于重庆某TBM区间隧道下穿一电缆隧道的工程实例,建立三维弹塑性有限元模型,模拟了TBM隧道掘进与既有电缆隧道之间的相互影响,对掘进过程中引起的电缆隧道变形及内力变化规律进行了分析与探讨,得出本项目安全评估结论,并提出优化设计的建议,可为以后类似工程的设计与施工提供参考。
With the project of a certain tunnel undererossing a cable tunnel as a practical example, a three-dimensional elasticity-plasticity simulation mode/is established to simulate the interaction between the tunnel being drilled and the existing tunnel in the paper,with the deformation of the cable tunnel and the law of the change in the internal forces of it analyzed and explored, the safety-evaluating conclusion of the project obtained, and suggestions on the optimization of the design put forward. The paper may serve as a useful reference for the design and construction of other similar projects.
