With the development of urban construction and the expansion of highway,tunneling goes much longer and deeper,which makes the stability of wall rock crucial in the design and construction of the tunnel project. The paper deals with the stability influencing factors,destabilizing mechanism and destability judgment basis of tunneling wall rock to provide theoretical basis for the working out of tunneling scheme and the selecting of tunneling support.
