Experimental study of interaction between cemented soil and shape steel of shaped steel reinforced cemented soil composite beam

Shaped steel reinforced cemented soil retaining wall is now used in engineering.However,there has been no systematic research on its failure mode.Unlike the traditional SMW method whose stiffness mostly depends on that of shaped steel,the stiffness of shaped steel reinforced cemented soil retaining wall mostly comes from cemented soil.In order to study the failure mode of shaped steel reinforced cemented soil retaining wall,composite beam tests were performed with steel board as shaped steel in mode composite beam.Model composite beams with different section height were tested with 2 kinds of loading scheme to analyze the assembled stiffness and ultimate bearing capacity of steel board-cement soil beam composite.
