| 摘 要： | 采用接触问题的拉格朗日乘子算法对隧道围岩与支护结构之间的界面效应进行了分析，对不同开挖步序下实际监测、考虑接触算法的FEM、不考虑接触算法的FEM三种方法所得拱顶下沉结果进行了对比分析，结果和实际现场的综合分析结论是一致的。

| Abstract: | The effect of interface between ground rock and support on the arch settlement by means of the .Lagrange multipher contact algorithm. The value and rule of arch settlements at different excavation stage, resulted from measurement, FEM on account of interface effect, FEM with no account of interface effect are compared. The conclusion is confirmed by measured arch settlement and comprehensive observation and analysis in construction site. |
