| 摘 要： | 根据梁与地基之间的内力变形协调关系推导出考虑摩擦效应的文克尔弹性地基上杆系有单元法的单元刚度矩阵，计算分析表明，当地基比较坚 硬且人的接触较为粗糙是时，摩擦效应将会较显著地减小结的内力与变形。

| Abstract: | In this paper,the element stiffness matrix which consider the contact factional effect is deduced.The computed result shows that, when the subgrade is hard, meanwhile the contact among the subgrade and the beam is coarse, the displacement and the stress of the beam will be reduced considerably. |
