东门关隧道进口段施工动态数值模拟分析

Numerical Simulation of Dynamic Excavation Construction Process of Entrance Portion of Dongmenguan Tunnel

根据东门关隧道开挖施工的特点,运用有限元分析方法,对其进口断面台阶法施工的过程进行了动态数值模拟分析,以指导隧道信息化施工。

On basis of the features of the excavation construction of Dongmenguan tunnel, the article makes a numerical simulation on the top heading/beneh eonstruetion of the entranee portion of the tunnel so as to provide guidanee for the information feedback construction.
