| 摘 要： | 利用锚索抗拔及预应力损失现场试验方法，测试了岩质边坡和类土质边坡的锚固能力及锚索预应力的损失，并计算得到了不同地层中的粘结强度，绘制出锚固体的荷载-位移曲线。试验结果表明，硬岩地层中仅须锚固2～4 m就能提供近 1 000 kN的锚固力；采用20 %～25 % 的超张拉即能达到锚索设计中锚固力的要求。同时，通过锚索的变形与刚度的分析，为类土质边坡锚固工程的设计提供了合理的刚度参数。

| Abstract: | Based on the field test of anchor cable pulling and prestress losses, the anchor forces and prestress losses of rock slope and similar soil slope were tested. It was observed that the force of 1 000 kN was put by anchoring in depth of 2-4 m in hard rock, and pulling prestress in 20 to 25 percent was required, which satisfy the design criterion. Bonding strength of various rocks and soils and curve of load and displacement in anchor were presented. And the stiffness and deformation were calculated. It provides reasonable stiffness for the design of anchor cable in similar soil slope. |
