| 摘 要： | 以福建漳州港尾铁路复合地基处理工程为背景,探讨了桩间距和桩长对路基路堤边坡稳定和工后沉降的影响,分析了桩间距不变、长短桩结合设置工况下路基稳定系数、复合地基承载力、工后沉降的变化情况,以寻求最经济合理的处理方案。结果表明:国铁Ⅱ级铁路采用长短桩结合设置的多向水泥搅拌桩加固处理软土地基的方案合理、可行,且较为经济。

Design Research on Optimization of Multidirectional Cement Mixing Pile in Deep Silt Soft Soil Area |
| |
| Abstract: | With the background of composite foundation treatment engineering in Fujian Zhangzhou Gangwei Railway, the influence of pile spacing and pile length on the side slope stability of subgrade embankment and post-construction settlement was discussed, and the change condition of stability coefficient, composite foundation bearing capacity, post-construction settlement under the condition with same pile spacing and mixed arrangement of long and short pile was analyzed so as to seek the most economical and reasonable treatment scheme. The results show that it’s reasonable, feasible and economical to adopt long and short pile mixed multidirectional cement mixing pile for reinforcing the soft soil foundation in national railway Class II railway. |
