摘要
以成都市川大华西校区过街隧道盾构施工为项目依托,对过街隧道上方地表及下方地铁隧道变形情况进行现场监测,并结合有限元数值分析对过街隧道的盾构施工过程进行三维数值模拟,结合现场实测结果进行对比分析和影响评估。
This paper relies on the shield construction of the crossing tunnel in Sichuan university West campus in Chengdu. Through monitoring the deformation of road above the crossing tunnel and metro tunnel below; and combining with the finite element numerical simulation to simulate the shield tunnel construction process of crossing tunnel by 3D-FEM; com- bined with field measurement results comparative analysis and impact assessment are carried out.
