| 摘 要： | 应用深梁理论，分析了受均布荷载悬臂梁与刚性地基接触的全过程。消队 了接触区间端占的集中反力，其接触区间明显大于只考虑剪切变形的梁理论的结果，揭示了横正应对梁的接触问题有着不可忽略的影响。

| Abstract: | The whole process of the uniformly loaded cantilever beam in contact with the rigid base is analysed by appling a deep beam theory.The concentracted pressure in the end of the contact range is eliminated.The lenth of the contact range is evidently longer than the lenth obtained by theories which only consider the effect of transverse shear deformation.It is pointed out that effect of transversal normal strain on the contact problem of beam can not be neglect. |

| Keywords: | contact stress transversal normal strain deep beam theory |
