根据锚固体与井壁面之间的剪切位移结构关系，应用荷载传递函数法建立了弹塑性理论空间模型，研究了预应力锚的拉载P与位移S的关系，推导出了预应力锚索的P-S曲线理论公式。通过对6根埋设在黄土层中的预应力锚杆进行现场拉拔试验，得到了锚杆的现场实测P-S曲线，并与试验结果进行了比较，结果表明，理论计算的P-S曲线与试验结果较为吻合。
Based on the shearing displacement structural relationship between the anchoring body and borehole wall face,the load transmission function method was applied to establish the elastic and plastic theoretical space model and the study on the relationship between the pulling load P and displacement S of the pre-stressed anchor was conducted.The P-S curve theoretical formula of the pre-stressed anchor was obtained.With the site pulling test conducted on the six pre-stressed anchors buried in the loess layer,a site measured P-S curve of the anchors was obtained.The comparison showed that theoretical calculation results of the P-S curve was relatively fit to the test results.
