摘要
利用三维弹塑性有限元法模拟了隧道施工过程中,管线的动态响应,通过数值模拟分析、现场量测的地表沉降值的对比分析可知,二者的数据基本吻合,论证了文中分析结果的合理性和可靠性,并对施工期间管线的安全性做出了评价,为该工程顺利实施提供了理论依据和指导作用。
The 3-D FEM coupling analysis model of tunnel supporting - soil - underground pipeline is established. Deformation and internal force of buried pipeline are specially analysed by numerical simulation of tunnel excavation and the safety of the pipeline is also forecasted. The rationality and reliability are proved by contrast of numerical simulation and spot measurement. Theoretical basis and guidance are provided for the practical projects.
