| 摘 要： | 根据深部岩体的变形特征，建立了弹塑性力学本构模型，采用有限单元法对进路顶板的稳定性进行了模拟计算，得出进路两帮为充填体时的顶板充填体垂直位移（挠度）要比两帮为矿体时要小，其稳定性也相对较好，结果较好地反映了进路顶板充填体的稳定性的实际情况，为设计和施工提供了一定的参考。

| Abstract: | According to the characteristic of the deep rock massdeformation,the elastic-plastic constitutive model is constructed.The stability of drift is analyzed with the finite-element method,from which the vertical displacement of the drift with both sides the back filling body less than with the ore are obtained,and the stability of it is better.The result of numerical simulation is agreeable to the practice;it will be valuable to guide engineering construction. |
