Soil arching effect is important for stabilizing the soil behind antisliding pile. The creep of soil mass will inevitably lead to the formation of soil arching

which has time effect. In this analysis

an indoor thrustpile model test is proposed. The characteristics of stress distribution in the soil and the time effect of soil arching behind antisliding pile are analyzed. The experimental data acquired by the soil pressure cells arranged along the normal direction of the thrust show that soil arching effect is enhanced with the increase of thrust.The thickness of soil arch increases with time.And the data obtained by soil pressure cells arranged along the direction of the thrust show that the horizontal soil arching effect increases and then gradually extends.The scope of stress dispersion has very large growth along the normal direction as time goes on.
