摘　　要：为研究木薯茎秆力学特性沿茎秆方向的分布规律,对其进行了压缩、剪切、弯曲试验,以加载方向、茎秆直径为试验因素,以最大承载力为响应指标。结果表明:沿径向加载时,压缩力最大,剪切力次之,弯曲力最小;沿轴向加载时剪切力最小。同时,给出各方向加载情况下受力与茎秆直径的线性方程。In order to research the regular pattern of the mechanical characteristics of cassava stem along the stalk , the tests develop by compression , shear and bending .The loading direction , stem diameter as the factors , the maximum ca-pacity force as indicators of response .The results showed that along the radial load maximum capacity force compression first, followed by shear and bending , along the axial load shear force minimum .And given the linear equation of force and stalk diameter .
