Abstract: Three kinds of reinforced soil with different structures of reinforcement (strap,perpendicular strap and net ) are tested in triaxl test on their shearing strength.The mechanism of the influence of reinforcement structure on the shearing properties of reinforced soil is analyzed.It is suggested that the elastic plastic model can be used as the model representing the stress strain relation for reinforced soil.And the parameters of elastic plastic models for three reinforced soils are given in

Key words: reinforced soil, shearing strength, stress strain model

摘要： 用大三轴试验研究了三种构造形式筋材(条带式、双向垂直条带式、网)的加筋土的抗剪强度参数，分析了筋 材构造对其土体强度特性影响的机理，建议了用双曲线模型作为复合加筋土的本构模型，并得出了三种筋材的加 筋土的本构模型参数
