| 摘 要： | 高原碎石土力学成因比较特殊，且在西藏高原地区分布十分广泛碎石土边坡的稳定性问题又与碎石土的抗剪强度密切相关，因此科学地开展碎石土的力学试验，准确地获取其抗剪强度指标是解决工程中碎石土强度问题的基础。详细阐述碎石土大型剪切试验的国内外研究现状，采用大型室内及现场两用直剪仪分析西藏邦铺矿区碎石土力学性质。并结合大型剪切试验、室内试验成果、理论公式，利用国际知名软件FLAC3D建立地质模型，分析了西藏邦铺北东碎石土边坡稳定性，为同类型碎石土地区边坡稳定性分析提供了可行的研究方法。

| Abstract: | Plateau gravel soil is widely distributed in the Tibet Plateau. The shear strength of gravel soil is closely related with the stability of slope. In the present research, large-scale shear tests on gravel soils in China and abroad are reviewed firstly. By using the large-scale indoor and field dual-purpose direct shear apparatus, the mechanical properties of gravel soils in Bangpu mining area in Tibet are analyzed.Furthermore, in association with direct shear test and indoor test results as well as theoretical formulas, a geological model is established in FLAC3D to analyze the slope stability in this area. The research results offer a feasible method for similar analysis on gravel soils. |
