| 摘 要： | 由于桩-网复合地基的结构形式比较复杂,难以采用解析法求得其应力和位移。利用有限差分法对某桩-网法路堤进行了数值模拟,并取得了较好结果。计算结果显示,桩间土沉降线为悬链线,与现场位移监测结果吻合较好;桩身弯矩和桩土应力反映了桩-网复合地基的一些受力机理。分析认为,桩间土沉降较大的主要原因是由土体本身压缩及桩侧弯引起的。

| Abstract: | A finite difference method was used to simulate a geosynthetic-reinforced pile supported embankment and the satisfied results are attained.The findings show that the settlement of soil between pile caps look like catenary shape and numerical values meet measured values well.Through the figures of moments along pile shaft and vertical stress above pile caps,some principle of the geosyntheitc-reinforced pile-supported embankment can be seen;and what cause the settlement between piles are the soil consolidation and the lateral move of piles. |
