摘要
运用岩土工程有限元软件Plaxis 2D建立平面应变模型,对路基工程中应用的水泥粉煤灰碎石桩与加筋垫层联合处理的软土路基进行分析。通过改变布桩范围,分析复合地基水平坡脚外地表、坡脚下一定深度及软土路基横断面上的水平向变形特性,所得结论为工程设计提供理论依据。
Plane strain model is established using finite element software Plaxis 2D of geotechnical engineering to analyze the soft soil foundation reinforced by cement-flyash gravel pile together with reinforced cushion in subgrade engineering. By changing pile layout, the horizontal deformation characteristics on the outer surface of and a certain depth below slope toe of composite foundation and on the section of soft foundation. The conclusion provides theoretical evidence for engineering design.
