采用有限元软件建立CFG 桩处治公路软土路基模型,分析桩间距、桩长和桩身模量与公路软基顶面最大沉降量的关系,提出公路软基均衡沉降控制标准。结果表明,路基顶面最大沉降量随着CFG 桩桩间距的增加而逐渐增大,随着桩长和桩身模量的增加而逐渐减小;对公路软基顶面最大沉降量影响最大的是CFG 桩的桩间距,将桩间距作为CFG 桩处治公路软基沉降控制标准;提出了不同CFG 桩桩间距组合的公路软基均衡沉降控制标准。

To propose a control standard of highway soft ground isostatic settlement, the relationships of the pile spacing, length, modulus and the maximum settlement on the top soft ground are analyzed using the established CFG pile treatment model of highway soft ground by ANSYS finite element. The results show that with the increase of CFG pile spacing the maximum settlement on the top soft ground increases correspondingly, while the maximum settlement on the top soft ground reduces correspondingly with the increase of length and modulus. The greatest impact on the maximum settlement on the top soft ground is the CFG pile spacing, therefore the pile spacing is taken as the control standard of CFG Pile treatment of highway soft ground settlement. Different control standards of highway soft ground isostatic settlement of combinations of CFG pile spacings are proposed.
