With the increase of the anchorage length of the anchor rod, the ultimate pull - out resistance of the anchor rod does not increase linearly, but is less and less obvious by gradual increase.
锚杆随着锚固长度的增加，极限抗拔力并不是线性增加的，而是增加得越来越不明显。

To study the reinforcement mechanism of the rock anchor, the test model was made simulating the real conditions and the pull test was done under the static load.
为研究钢管岩石锚杆的锚固机理，模拟实际情况制作试验模型并进行了静载作用下模型的拉拔试验。

This paper presents a computation method for a new type of retaining structure-the anchor pile with a pull rod.
