摘要
从理论上讨论了弹性、弹塑性和流变岩体中隧道的变形特征，给出了隧道变形随地压和时间的变化规律，为预测方法的研究提供了理论根据。在讨论滑坡引起隧道变形开裂特征的基础上，着重分析了单滑面和多滑面滑坡中隧道的变形规律。在预测方法中提出了应首先评估被预测隧道的允许位移与变形量，给出了评估位移及变形量的方法。给出了建立预测时的计算分析方法即位移反分析法、弹塑性和粘弹塑性正演分析法。
The deformation characters of tunnel in elastical, elasto-plastical and rheological rock mass are discussed in theory. The change laws of tunnel deformation with pressure and time are given to get the theory basis for study of forecasting methods. The deformation laws of tunnel with single and couple slip surfaces of landslide are analyzed especially. The allowed displacement and deformation values of forecasted tunnel are evaluated with some ways. At last, some calculation and analysis methods for forecasting are given.
