斜坡桥梁桩基础加固优化设计

Optimization design of bridge pile foundation in slope area

    摘要
  • 摘要: 山区公路建设,由于工程地质条件复杂,上部结构荷载大,传统工法难以很好解决桥梁桩基础大变形问题。利用三维有限元数值模拟,对人工挖孔桩基础的加固方案进行模拟分析与研究,给出了水平位移、沉降量等模拟结果。根据数值模拟的结果,分析了锚杆(索)在加固桩基础中的作用与效果。结果显示,锚杆(索)加固桩基础可以有效减小水平位移和沉降量,大大降低工程投资,且为类似工程优化设计提供了一条很好的思路。

     

    Abstract: Because of complicated engineering geology conditions and big load of upper structure in road construction of mountainous area,large deformation of bridge pile foundation appears,and the problem can not be solved very well.So deformation control of bridge pile foundation is very important in high frusta bridge design.Artificial dug pile foundation have been simulated by three-dimensional finite element method in the paper,then horizontal displacement and settlement were given.According to numerical simulation results,reinforced function and effect have been analyzed,horizontal displacement and settlement of pile foundation which have been reinforced by anchor pole(cable) were reduced effectively,and its project investment was reduced largely,and then the method provided a good way for similar projects.
