Settlement Analysis of Soft Foundation Treated by Cement-Soil Mixing Pile Based on Stiffness Theory
Based on a high-filled soft foundation,this paper analyzed the influences of different elastic moduli and pile diameters on the settlement of the filled embankment according to the statement of the stiffness theory.The simulation results indicated that the road settlement under each working condition showed a trend of large in the middle and small on both sides.The smaller the elastic modulus,the larger the surface differential settlement.When the elastic modulus of the mixing pile or the pile diameter increased,the maximum settlement difference of the road surface gradually decreased.Regarding the objective law of road settlement,this paper analyzed and verified the principle of road differential settlement.
