Abstract:

Based on model tests and mechanical calculation, destruction mechanisms and forms of tunnel are analyzed. Taking safety factors calculated by strength reduction finite element method as the stability criterion is put forward. The stability marks of all kinds of rock masses are put forward in all kinds of surrounding rock classifications. Based on the above, the stability marks of all kinds of rock masses, especially one kind of new quantitative symbol, which is using safety factors of rock masses in non-lined situation as quantitative symbol is proposed. Based on the given corresponding safety factors, the strength parameters of rock masses for improving the accuracy of the strength parameters are deduced. The computational methods of designing rock tunnel, calculating safety factor of rock masses and lining work by strength reduction FEM and FEM respectively are proposed. In addition, the numerical calculation to one Qingdao underground work is carried on, and the safety factors of rock masses and lining work are calculated respectively. The initial standards of designing rock tunnel is that after initial lining, the safety factor of the rock masses is not less than 1.15 to 1.2, and the safety factor of initial lining is not less than 1.3; the safety factor of the rock masses is greater than 1.25 and the safty factor of lining is greater than 2.0 to 2.4 after the second lining, which ensure the tunnel security during construction and operation

Key words: tunnel, stability of surrounding rock, strength parameter, safety factor, lining support structure, initial lining, secondary lining
