摘要
通过对阿尔及利亚东西高速公路M1和M2标白垩系泥灰岩的结构面、矿物成分、抗压抗剪强度、破碎及降解系数等物理力学指标的统计分析,揭示其工程特性,按法国规范进行GTR分类,概略地提出了路堑宽平台缓边坡、路堤强化基底处理和边坡加固相结合的设计对策。
Through analysis on physical and mechanical index such as structural face,mineral composition,compressive and shear strength,fracture and degradation coefficient of cretaceous marlite in M1 and M2 section of Algeria East-West Expressway,the engineering characteristics of marlite is exposed and it is classified into GTR category by France Specifications.The design measure of wide platform and gentle slope for cutting excavation,reinforced subbase for embankment combined with slope reinforcement is put forward.
