| 摘 要： | 通过深圳地铁五号线既有桥梁桩基主动托换顶升过程中的现场实测数据的分析,发现在桩基托换过程中,荷载级数与桩体变形存在近似的线性关系。结合顶升过程的实测数据,利用有限元软件MIDAS对顶升过程进行了模拟,模拟数据与实测数据基本相似。

| Abstract: | Through analysis on site measured data during active underpinning of pile foundation of the existing bridges in No.5 line of Shenzhen Metro,it is found that during underpinning of pile foundation,load series and pile deformation are in similar linear relation.Combined with site measured data during jacking-up,jacking process is simulated using finite element MIDAS software.Simulated data is basically similar to measured data. |

| Keywords: | pile foundation underpinning jacking up load displacement deformation |
