%X According to  centrifuge test results on the composite structure of masonry and reinforced soil retaining walls,numerical models were built by ABAQUS to study the influence of reinforcement spacing  and modulus on the deformation characteristics and the soil pressure distribution of this composite structure. It is found that small  reinforcement spacing  and larger  reinforcement modulus have  better reinforcement effect in controlling the deformation of retaining walls considering the variation range of parameters in this research. Due to the soil arch effect in the filling zone of masonry retaining wall,the soil pressure distribution in the upper part of  reinforced retaining walls is different from that of conventional walls,and the masonry retaining wall can be regarded as a solid foundation as long as reinforced retaining wall is high enough. Moreover, the deformation of this composite structure mainly occurs in  the construction period,so enough attention should be paid to controlling the construction quality.
