| 摘 要： | 本文根据拟线性偏微分方程组的特征线理论，求得无重双曲、抛物Ｍｏｈｒ－Ｃｏｕｌｏｍｂ体边坡极限荷载的解析解．用两参数的双曲线和抛物线可以较好拟合由实验提供的破坏曲线．由其解发现屈服准则和坡角对极限荷载影响很大，理想塑性体的极限荷载也非最小．

| Abstract: | The analytical solutions of limit loading for weightless slopes of Mohr-Coulomb material doscribed by hyperbolic and parabolic yielding criteria are obtained based on the characteristic line theory of quasi-linear partial differential equations. The hyperbola and parabola with two parameters are able to represent the experimental failure curves. It is shown that yielding criteria and slope angle have significant influence on the limit loading of a slope. While. the limit haling of slopes of perfectly plastic material is not the minimum. |
