摘要
新奥法是目前应用较广泛的隧道施工技术,以新奥法施工过程中围岩壁面间水平内空变形实际量测值为实验数据,应用回归分析方法建立最佳数学模型。所得回归函数模型与实测数据的相关系数较高,残差较低,拟合情况良好,能有效地反应隧道内空变形规律。最后对变形终值进行预测,为隧道施工安全管理与预警提供监测依据。
New Austrian Tunneling Method (NATM) is currently widely used in tunnel construction technology. Taking the measured data of the deformation in NATM construction process between the horizontal rock wall as experimental date, the regression analysis of establishing the best mathematical model is applied. The resulting regression function model with the measured data correlation coefficient is higher,lower residue,fit well and be able to react effectively the tunnel deformation law. Finally, the final value of deformation is predicted, providing the basis for monitoring the tunnel construction safety management and early warning.
