摘要: 复理石地层在全世界分布广泛,属于典型的韵律互层结构,具有明显的沉积构造与层理特征,且岩层之间差异风化,加之岩体节理发育。为了满足国际工程中对复理石地层边坡稳定性分析的需要,基于Hoek-Brown强度破坏准则,可以获取准确的岩体强度设计参数,同时,利用工程测绘和工程勘察数据,基于运动学和赤平极射投影原理,可以综合确定复理石岩质边坡的破坏模式。本文以实际工程为依托,通过研究表明,使用的边坡分析方法能够准确地确定场区边坡破坏模式,为进一步边坡设计提供依据。该方法普遍被国际项目业主认可,在今后类似边坡工程中具有重要的借鉴意义。
Abstract: Flysch deposits are widely distributed all over the world. They are typical alternations interlayer deposits, which have obvious sedimentary structures and bedding characteristics. Differential weather between layers makes rock mass joints development. In order to analyze and evaluate the slope stability of flysch deposits for the international project, based on the Hoek-Brown failure criterion, the realistic rock mass strength parameters can be obtained firstly. On the other hand, by using geological mapping data and geotechnical investigation results, based on kinematic theory and hemispherical projection method, the main slope failure model can be determined. The above methodology was proved and used in practical projects, also, the method can provide the principle for the slope design. Furthermore, this procedure is recognized by oversea clients and can be important reference in the similar slope project.
