| 摘 要： | 对目前施工期边坡稳定分析中通常采用的抗剪强度进行分析,施工期的地基土强度除应考虑施工过程的填土对地基的固结作用外,还应考虑施工期间地基土在自重条件下的固结作用,并建议采用分别考虑填土重力和地基土自重力的固结度所计算的强度。另外,采用垂直附加应力计算强度时,不符合稳定性分析的应力状态应是极限应力状态的极限状态设计原则,采用土条重力计算强度更为合理。 |
| 关 键 词： | 施工期 边坡稳定 饱和软土 固结作用 强度 |

| Abstract: | The shear strength commonly used for stability analysis of a slope during construction is analyzed ; for the strength of foundation soil during construction period, the effect of consolidation caused by dead weight should be considered besides the effect of consolidation caused by fill, and it is recommended to use the strength calculated by considering the consolida- tion degree of fill weight and seff-weight respectively. In addition, calculating the strength with vertical additional stress does not conform to the limit state design approach and it is considered that the stress state for stability analysis should be boundary state of stress, it is more reasonable to make calculation by using soil bounds gravity. |
| Keywords: | construction period slope stability saturated soft soil consolidation effect strength |
