摘　　要：对于采用无砂混凝土小桩处理的高速公路拓宽工程,建立有限元分析计算模型,分析了采用无砂混凝土小桩处理的高速公路拓宽工程的地基及填方路基的变形性状,以及桩长变化对地基及填方路基沉降的影响,对高速公路拓宽工程具有一定的指导意义。For the expressway widening engineering treated with small non-sand concrete pile, a finite element calculation model is established. The deformation features of the ground work and filling area treated with small non-sand concrete plies in expressway widening engineering, and the influence of the changes of pile length on the settlement of foundation and filling subgrade are analyzed. The results have certain guiding significance to the widening of expressway.
