前言目前,加筋土挡墙加筋最大拉力的计算方法大多是采用库仑和朗金理论导出。两种不同的理论可导出各种计算加筋拉力的表达式。主要区别是:一类是楔体分析法,以库仑理论为基础,视加筋土为复合体,在侧压力作用下墙面绕墙趾向外旋转,形成主动土压状态,破裂面与垂直线之间的夹角为θ(θ视加筋土挡墙的边界条件而异)。另一类是应力分析法,以
Foreword At present, the calculation method of the maximum tensile force of reinforced earth retaining wall is mostly derived by Coulomb and Longjin theory. Two different theories can derive various expressions for calculating tensile stress. The main difference is: one is the wedge analysis method, based on coulomb theory, considering the reinforced soil as a composite body, the wall rotates outward around the wall toe under the action of lateral pressure to form an active earth pressure state with rupture plane and vertical The angle between the lines is θ (θ depends on the boundary conditions of the reinforced earth retaining wall). The other is stress analysis method
