石灰改良土填筑的路基,强度高、稳定性良好,与传统路基相比,坡率更大、路基土方工程量和造价更低,但石灰改良土填筑路堤结构边坡坡率的确定方法尚不明确。阐述了石灰改良土边坡强度的形成机理及微观特性,利用Geo-Slope软件建立理想边坡模型并对边坡稳定性随着边坡坡率以及边坡高度变化的规律进行了探讨,结合某省两个不同场区的边坡工程实例,总结了不同坡率和高度对工程稳定的影响并提出了合理的坡率。
Lime improved soil filled embankment, high strength, good stability, compared with the traditional roadbed, the slope is greater, the amount of earthwork and lower cost of subgrade, but lime to improve the slope of embankment slope filling method to determine still uncertain. The forming mechanism and microscopic characteristics of the slope strength of lime-improved soil are expounded. The ideal slope model is established by using Geo-Slope software and the stability of the slope is discussed with the slope slope and the height of the slope. Two different fields in the province of slope engineering examples, summarizes the different slope and height of the impact on the stability of the project and put forward a reasonable slope.
