Study on Stability of Stratified Rock Tunnel

ZHOU Ying-lin,QIU Xi-hua(Hunan Corporation of Road and Bridge,Changsha 410004,China)  
Mechanical characteristics of stratified rock tunnel are firstly analyzed in this paper.Then the failure mechanism of stratified rock and its four typical unstabilized models are also brought forward in this paper.Furthermore,the mechanical characteristics of support structure are simulated with FEM program based on the Guankouya highway tunnel.The mechanical characteristics of surrounding rock with different attitude and the most unfavorable zone of its corresponding secondary lining are summarized,which are valuable to the design and construction of stratified rock tunnel.
