Abstract: Shaped steel reinforced cemented soil retaining wall can be used when the depth of excavation is suitable. However, there is not much research about its failure mode and assembled stiffness. The stiffness of shaped steel reinforced cemented soil retaining wall mostly comes from cemented soil, where about the stiffness of traditional SMW depends mostly on the stiffness of shaped steel. Bending tests were performed on 6 model composite beams with different cross section heights and with steel board as reinforcement. 2 kinds of loading scheme were adopted. The failure mechanism, assembled stiffness and ultimate bending bearing capacity of steel board reinforced cement soil beam composite were analyzed. Based on testing results and correlative analysis, the evolution of bending stiffness of composite beam can be clarified into two stages and the method to evaluate the bending stiffness at these two stages were suggested. The bending stiffness at the end of 1st stage is recommended to be used to predict the displacement of shaped steel reinforced cemented soil retaining wall when the factor of safety is satisfied.

Key words: reinforced cemented soil, composite beam, retaining wall, assembled stiffness, failure mode
