【摘要】 在现有几种锚杆数值分析方法的基础上,对考虑了灌浆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,并结合例子对灌浆锚杆的变形应力规律进行了分析.更多还原

【Abstract】 This dissertation reviews several bolt numerical simulating methods which are used at present, and makes special research to the theory and applicability of the 3-D bolt element 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 makes special research to bolt’s mechanics characteristics.更多还原
