| 摘 要： | 对纤维混凝土中应力传递机制问题作了分析研究，将应力和位移看作一组“初等解”和一组“修正解”的叠加，“初等解”即为一般的二维理论所得的解答，而“修正解”应用拉甫（Love)位移函数法求得，计算实例表明，解的收敛性良好，将三维弹性理论解与剪滞法的解比较后，可见两种解存在较明显的差别。

| Abstract: | The stress transfer mechanism of steel fibre reinforced concreteis studied. The solutions for the stress and displacement were regarded as the superposition of “the elementary solutions” and “the improved solutions”. The elementary solutions were found by using two dimensional elastic theory and the improved solutions were found by using the Love displacement function method. The calculated results indicate that the solutions possess good convergence. By comparing the three-dimensional solutions with the shear-lag solutions, evident difference may be found. |
