Abstract

Stratum permeability affects the consolidation of shield tunnel simultaneous grouting，thus affecting the segments uplift during construction period. Since the analysis of shield tunnel segment uplift during tunnel construction does not consider the impact of strata permeability，assuming the grout of simultaneous grouting as Newtonian fluid and the soil as porous media and applying the theory of penetration mechanics and fluid mechanics，a calculation method for the consolidation time of simultaneous grout under the condition of filtration effect in permeable stratum was proposed. Then the equivalent continuous beam model for shield tunnel segment uplift analysis during tunnel construction was revised by putting the consolidation time and the properties of simultaneous grout，excavating velocity into the length of unconsolidated zone in the equivalent continuous beam model. Thus an equivalent beam model for shield tunnel segment uplift calculation considering the consolidation properties of simultaneous grout under the condition of filtration effect in permeable stratum was established and FEM programing was employed to solve this model. The rule of shield tunnel segment uplift during tunnel construction in stratum of silty sand and cobble，sand and silty clay in Nanning was investigated based on this model. And the result shows as follows：The equivalent beam model considering the effect of stratum permeability further reveals the mechanism for the formation characteristics influencing segments uplift. Besides，the calculation results match well with the measured data in situ and the model is more suitable for segment uplift analysis in different permeability stratum. Meanwhile，we draw the conclusion that the weaker the stratum permeability，the longer consolidation time for simultaneous grout，the longer dissipation time for simultaneous grout pressure and the greater the magnitude of tunnel segment uplift.

Key words： tunnelling engineering shield tunnel segment uplift equivalent beam filtration effect
