| 摘 要： | 基于G106国道的实测数据，讨论了拱顶沉降和周边收敛随掌子面掘进深度的变化规律，并利用回归分析进行了拟合。通过实测数据与拟合结果的对比表明：拱顶下沉与周边收敛均随着掌子面的掘进深度呈非线性变化关系。

| Abstract: | According to the crown settlement and the surroundding convergence of G106 highway tunnel measurement data,we discussed the crown settlement and the surroundding convergence which changed with the tunnelling footage of tunnel face in law,and used regression analysis to fit them.The measured data and the analysised data show that the crown settlement and the surroundding convergence change with the tunnelling footage of tunnel face and present a low of nonlinear. |
