This paper makes the fitting analysis of the field test data according to the hyperbolic model established by the interface spring theory,and simulates the experiment of bolt upraising by means of the finite element method.After the comparison of the calculated results with the field test results,the paper draws the main conclusion that good fitting effect can be obtained when the hyperbolic model is adopted in fitting the relationship between axial force and depth.The interfacial shearing stiffness will so...

文章按照界面弹簧理论所建立的双曲线模型，对试验实测数据进行了拟合分析，并采用有限元法对锚杆上拔试验进行了模拟，对比计算结果和实测结果得出的主要结论为：采用双曲线模型拟合锚固轴力随深度变化的曲线，可以取得良好的拟合效果；在逐级加载的条件下，界面的剪切刚度呈软化的趋势；在锚固界面没有发生较大滑移的情况下，计算位移和实测位移比较接近。
