| 摘 要： | 路基的填土高度对于桥台基础的受力和变位有着重要影响，特别是在黄土地区修建的桥梁，这种影响表现则尤为突出．针对在湿陷性黄土地区一座高填方路段上的桥梁，建立了桥台桩基础三维弹塑性有限元分析模型，采用ANSYS软件进行模拟，分析了当路堤在填方高度不同、基础在不同桩长、不同桩径的条件下，桥台基础沉降的变化情况，探索了路基的填方高度、基础的桩长、桩径的变化对桥台桩基沉降的影响规律，得到几点关于桥台基础设计有益的结论，可为高填方路段的桥梁设计提供参考．

| Abstract: | The height of embankment has great effects on force and displacement of the pile foundation on abutment.Especially when the bridge is built on the loess area,the impact is prominent.Based on a bridge which has a high embankment and is built on the loess area,3-D elasto-plastic finite element of the pile foundation on abutment has been established in this paper.Using the ANSYS software,settlement variation of the pile foundation on abutment has been analysed based on the condition of different heights of bac... |
