| 摘 要： | 本文采用有限元法对预应力锚索外锚固十字梁传力格构进行了三维应力分析。预应力锚索加固方法在防止边坡滑塌、倾倒、剥落等方面发挥重要作用，作为其主要构造之一的传力结构具有集中荷载传递到坡面（岩面）和调整坡面（岩面）受力方向的作用。本文分析了该“十字梁格构”传力结构的应力状态，总结了其在边坡锚固中的受力特点。

| Abstract: | A 3-D stress analysis on cross-beam force transmission lattice for outer fixed end of pre-stressed anchorage cable is made herein with finite element method. The pre-stressed anchorage method plays an important role in the aspect of preventing slope sliding，collapse，flaking，etc.，for which the force transmission structure is one of the main structures and has an important function to concentrate the load transmission and adjust the stress direction of the slope face（or rock face）. The stress state of the cross-beam force transmission lattice is analyzed herein and then the mechanical characteristics of it during the anchorage of slope is summarized as well. |
