| 摘 要： | 应用PLAXIS非线性有限元软件,模拟了桩-网复合地基加宽路基的施工及加载过程,对加宽后路基的竖向位移、水平位移、应力及桩体应力进行了分析计算,分析结果证明桩-网复合地基很好地减小了路面的不均匀沉降及路基的水平变形,还有效地分散了路基填土荷载,增加了加宽路基的稳定性,得出格栅加筋层数的增加并不能很好地减小土体的水平位移,即采用一层格栅加桩基处理较为合适.

| Abstract: | Using PLAXIS nonlinear finite element software,this paper makes a simulation research on the construction and loading process to roadbed widened of pile composite foundation.In it the vertical displacement,horizontal displacement of thewidened roadbed,and the stress and the pile body is analyzed and calculated.The results show that the pile composite foundation is very good to reduce the uneven settlement and the horizontal change of the roadbed,to effectively disperse the loads of subgrade soil,and to incr... |
