Variation characteristics of tunnel adjacent rock and shotcrete rockbolt support action;

It shows that the adjacent rock is stable by analysis of influence and characteristics of stability of adjacent rock and support structure during construction.

Incorporated with practical construction experiences of Shijiagou tunnel,the performed core-soil sidestep construction scheme on the Ⅳ and Ⅴ grade adjacent rock were introduced from advanced support,upper,middle and down excavation,initial concrete spraying,upping steel frame,which expected to be referenced to the similar tunnel construction.
