| 摘 要： | 假定支盘桩直桩段的桩侧摩阻力和含有分支或承力盘桩段的等效侧摩阻力q与相应桩土相对位移s的关系可用双曲线函数表示,根据实测数据采用最小二乘法求出所需系数,并用所得的双曲线与实测各分段的q-s关系进行对比。结果表明,在各分段达到极限承载力前,q与s基本上符合双曲线关系,用该法可以估算各分段的极限摩阻力。 |
| 关 键 词： | 挤扩支盘桩 侧摩阻力 双曲线函数 |

| Abstract: | The load-settlement relationship of skin friction q of every part of squeezed branch and corresponding settlement s of plate pile is presupposed as hyperbolic function,the necessary parameters are obtained based on the measured data,and compared with q-s relationship of measured every part.The calculated curve is agree well with the measured curve before the ultimate load of every part.This indicates that this method can be used to estimate the ultimate skin friction resistance of every part of the pile. |
| Keywords: | squeezed branch and plate pile skin friction hyperbolic function |
