摘　　要： 将甘蔗茎秆简化成弹性杆件,土壤视为Winkler地基,采用切割器切割甘蔗时,将甘蔗茎秆做为侧向 受荷桩处理,采用传递矩阵方法,计算甘蔗茎秆的内力与变形。结果表明,人土切割时甘蔗茎秆的内力与变形明 显小于不入土切割,与实测结果相比较,计算值与实测值吻合程度较好。 The internal forces and distortions of the sugarcane stalk can be calculated by way of transference matrixes, taking the sugarcane stalk as a elastic bar and the soil as the Winkler foundation so as to consider the sugarcane stalk as a pile under the action of lateral load when cutting the sugarcane stalk with the basecutter. The internal forces and distortions for cutting under the ground are significantly smaller than that for cutting over the ground, and the results calculated have a good agreement with ...
