【摘要】 由于山区地形地貌的特点,在陡坡地形修建高等级公路时,现有路基结构形式难以保证环境与经济效益俱佳。因此,提出一种对自然山体扰动与破坏较小的双层行车路基结构,从环境影响、工程造价和施工难易等方面与现有路基结构进行对比,并利用ABAQUS有限元软件对4种可行的双层行车路基结构进行数值模拟,分析其静力特性。更多还原

【Abstract】 Building mountain highway in steep terrain,the existing subgrade structure is difficult to ensure both environmental and economic benefits are good due to the characteristics of mountainous topography.Therefore this paper proposes a new subgrade structure applicable to double-decker traffic which will cause less damage to the mountain natural environment, and compares with the existing subgrade structure from the aspects of the environmental impact,engineering cost and construction difficulty,analyzes the static characteristics of four feasible structural forms by finite element software ABAQUS.更多还原
