| 摘 要： | 基于相似理论在室内模型试验中的运用,对路堤荷载作用下桩帽式CFG桩复合地基、天然地基的承载特性进行了室内模型试验研究,同时运用数值分析软件对原型桩帽式CFG桩复合地基与天然地基的承载进行了模拟分析。结果表明:桩帽式CFG桩能充分发挥桩体的承载作用,同时能有效地控制黄土地基的沉降变形。

Study on Reinforcement Effect of CFG Pile with Cap on Loess Foundation under Embankment Load |
| |
| Abstract: | Based on application of the similarity theory in indoor model test, the bearing characteristics of cap-type CFG pile composite foundation and natural foundation, which are under the action of embankment load, were studied by indoor model tests, and by numerical analysis software based simulation on the both prototypes. The result shows that CFG pile with cap may give full play of its body for bearing, and control the settlement deformation of loess foundation effectively. |
