| 摘 要： | 为了合理设计高吨位预应力岩锚，必须清楚岩锚的应力场情况。本文采用非线性有限元法计算了胶结式预应力岩锚胶结体和基岩的应力及其分布。计算结果表明：锚根表面剪应力上大下小；对于岩石较硬的情况，同一断面上以钢丝束表面剪应力最大；最后破坏于胶结体内部。

| Abstract: | In order to design the prestressed rock anchor reasonably, it is necessary to know the stree-field. This paper calculates the stress distribution of prestressed rock anchor by the non-linear finite element method. The conclusion is that the shear stress on the surface of anchor-root is large in the upper part and dropping in the lower part;the shear stress on the surface of the steel cable is the largest at the same section for solid rock;the destruction is in the cementing body. |
