| 摘 要： | 通过有限元计算软件,对于超轻材料桩复合地基和普通复合地基处理极软地基的效果进行了对比分析。研究发现超轻材料桩符合地基因为采用粗而短的桩在处理极软地基方面具有明显的优势,其能够克服刚性材料桩桩体模量太大桩土不能协调变形的缺点,也能够克服柔性材料桩桩长较长而失稳的缺点。论文证明在数值模拟的前提下,超轻材料桩复合地基处理软基在处理效果和经济价值方面具有可行性。 |

| Abstract: | By using finite element software,the article comparatively analyzed the effect of super light material composite foundation with common material pile composite foundation.It found that super light material pile with the thick and short pile has obvious advantages,it is able to overcome the deficiency that pile and soil can’t coordinate deformation of rigid material pile with high modulus,and also be able to overcome the deficiency that pile instability of flexible material pile with the long piles.This paper provides the evidence of treating soft soil foundation with the super light material pile composite foundation on the feasible of effectiveness and economic value. |
| Keywords: | soft soil subgrade EPS composite foundation |
