Performance of Abutment with Geocell Reinforced Cement Soil Backfill
Unconfined compressive strength tests of soil with different cement dosage of stabilization have been conducted to determine the optimum cement stabilizing dosage. And, the shear strength and deformation of the geocell reinforced cement soil have been investigated through a serial of direct shear tests and plate-loading tests. The results show that there is a significant improvement on shear strength and modulus of the soil by reinforcement. Moreover, FEM has been used to simulate and analyze the performance of abutment with geocell reinforced cement soil backfill. And the comparison of the computing results to field testing results has been carried out. The research results indicate that: the abutment with wedge-shape geocell reinforced cement soil backfill has remarkable effect on decreasing the differential settlement on bridge-embankment transition section. The gradient of settlement along the longitudinal direction of bridge-embankment gets much more smooth-going and less.
