| 摘 要： | 本文通过假设一种粘结应力与滑移之间的关系,得出了粘结应力和滑移沿传递长度的分布规律,并指出,本文首次定义的构件常数是决定这两种分布的关键参数,它取决于构件的几何及物理特性,还能作为一个基本参数在今后的研究中得到应用。文中还导出了计算裂缝间距和宽度的公式,用该公式计算出的结果与试验的结果吻合较好。

| Abstract: | Distribution laws of bond stress and slip along transfer length are found by assuming the existence of a certain relationship between them. The segment constant which is defined for the first time by the authors and is dependent on geometrical and physical properties of the member is of basic importance to these distributions and can be used as an elementary parameter in further research. The results obtained are in good agreement with the measured values in the reference materials. |
