| 摘 要： | 基于水泥土挡土墙倾覆失稳机理的分析,提出可能倾覆的转动点不在墙趾的水泥土挡土墙抗倾覆稳定性分析方法。该法考虑了地基承载力大小的影响。计算结果表明,地基土内摩擦角越大,倾覆转动点越靠近墙趾,按本文定义的抗倾覆安全系数也越来越大,但始终小于现行规范方法的结果。

Analysis of overturning stability of cement-soil retaining wall |
| |
| Abstract: | Based on the analysis of overturning mechanism of cement soil retaining wall, a new evaluation method of its overturning stability is suggested, where the assumption that the rotation point of overturning is at the toe of wall is unnecessary. This method considers quantitatively the effect of the bearing capacity of the foundation on its overturning stability. The results illustrate that the greater the internal friction angle, the more the rotation point of overturning is close to the toe of the wall, and the greater the factor of overturning stability computed using the method in the paper, but the latter is always less than the result computed using the method of the current specification. |
