摘要
采用有限元方法对梅河高速公路代表性隧道———黄牛坳隧道LK74+613断面围岩的位移和稳定性进行结构计算;结合施工过程进行了LK74+613断面不同位置点的数值分析;动态模拟了该隧洞施工的全过程;对该公路隧道的围岩和支护结构的稳定性进行了合理的分析,为工程设计和施工过程提供了合理的参考。该研究对全线其它隧洞的设计和施工具有一定的参考作用。
Displacements and stability analysis of the surounding rocks of Huangniuao tunnel of Meihe express way are studied by selecting a section of LK74+613 sgment, which is one of the most typical tunnels of Mei_He express way. Numerical simulation by finite element method(FEM) in different places of the section is conducted according to the constrution process,and the whole constructing process is dynamically simulated. The results provid a scientific references for the design and construction of the tunnel engineering in Mei_He express way or any other similar enginerings.
