三维锚杆数值模拟方法研究

Developing the numerical simulating methods of the 3-D bolt

在现有几种锚杆数值分析方法的基础上,对考虑了浆体切向受力性态的三维锚杆单元理论及其应用进行了研究,编制了三维锚杆有限元计算程序,并结合例子对浆体锚杆的变形、应力规律进行了分析。计算结果显示了模型的可靠性和实用性。

This paper reviews several bolt numerical simulating methods which are being used at present,and does a special research to the theory and applicability of the three-dimensional bolt elements which takes the tangential mechanics properties of the grout into account. By means of the FEM and the models mentioned,the program is developed to simulate the bolt and the structure. Through an example,it make sspecial research on bolt's mechanical characteristics. The calculations illustrate the capabilities of the elements.
