| 摘 要： | 预应力锚杆支护技术广泛应用于边坡工程，但预应力锚杆的作用机理还缺乏系统深人的研究。通过利用ANSYS提供的非线性弹塑性模型，结合一边坡锚喷支护工程实例，采用基于摩尔-库伦等面积屈服准则的强度理论，对边坡支护前后的稳定性进行分析，对锚固件和边坡岩土体的相互作用进行数值模拟，得出一些有益的结论，对边坡锚喷支护工程优化设计具有一定的指导意义。

| Abstract: | Although pre-stress anchor bolt is widely used in slope engineering, the mechanism of anchor bolt is not studied thoroughly and systematically. By using the nonlinear plasticity Druker-Prager moder offered by ANSYS, combining a slope engineering case of anchor-plate retaining, with the strength theroy based on Mohr-Column eqivalent area circle yield criterion, some problems are discussed, including slope stability fore and after retaining interactive mechanism between anchor bolt and rock-soil mass. Finally, some profitable conclusions are presented, which would serve as guide to improve the design of slope anchor-plate retaining engineering. |
