| 摘 要： | 土工格栅加筋路堤在公路工程中有着广泛的应用前景，但由于加筋机理还不很清楚，具体设计方案还借助于经验，设计者必须充分了解其稳定性的主要影响因素和各影响因素对边坡稳定性的影响程度。为此，采用 Morgenstern-Price法对土工格栅加筋边坡稳定性与坡高、坡率、土的内摩擦角和粘聚力、加筋层间距、坡顶荷载和地震力等影响因素之间的关系进行了分析计算，得到了这些影响因素各自对边坡稳定性的影响规律，分析比较了边坡稳定安全系数对这些影响因素的敏感程度。

| Abstract: | Geogrid-reinforced embankment is expected to be used widely in highway engineering. But the current design methods are much relied on experience because the reinforcement mechanism is not clear now. The designer should understand the main effecting factors and their effecting degrees to the stability of a geogrid-reinforced slope. For this reason, the relationship is analyzed by Morgenstern- Price method between the stability of a geogrid-reinforced slope and the slope height, slope ratio, the soil＇s cohesion an internal friction angle, the reinforcement spacing, the surface load and the earth- quake forces. The manners how these factors affect the geogrid-reinforced slope stability are presented. The sensitivity of the slope stability to each effecting factor is analyzed and is compared one another. |
