| 摘 要： | 基于新奥法的基本原理，对东深供水改造工程凤岗隧洞越过广深公路的浅埋段的施工过程进行了有限元三维数值仿真分析，并和现场监测进行了比较。结论认为：有限元分析和隧洞围岩变形位移监测结果都表明隧洞设计的支护和施工方法是安全合理的；研究处于复杂地质条件下的浅埋隧洞的开挖和支护，对保证工程稳定，加快施工速度，节省工程投资具有重大意义。

| Abstract: | Based on the basic principles of NATM, three-dimensional finite element numerical emulation analysis of the shallow-buried reach of Fenggang Tunnel crossing Guangshen Highway in Dongshen Water Supply Project is conducted, and the analysis results are compared with on-site monitoring. The conclusions are drawn that shoring and construction methods of the tunnel design according to finite element analysis and displacement monitoring results of tunnel wall-rock deformation are safe and rational; research of excavation and shoring of shallow-buried tunnel under complicated geological conditions has great significance for engineering stabilization, speeding up construction, and saving project investment. |
