加筋水泥土组合梁型钢-水泥土相互作用试验研究

摘要

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 stud-y 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.%小规格型钢加筋水泥土结构作为挡土墙已应用于实际工程,但对于其组合破坏模式和刚度缺乏深入的研究.为研究加筋水泥土结构破坏模式,进行了室内采用钢板加筋的不同截面高度、不同加载方式的水泥土组合梁抗弯试验,分析了试验条件下钢板-水泥土组合梁的抗弯强度.
