Abstract: Making use of the load and displacement curve of anchor rod (shorted for P-S curve) acquired in the field pull-out tests, we can make sure the ultimate bearing capacity of anchor rod; but we must proceed destructiveness experiment. By developing the mathematical model research of the P-S curve of anchor rod, the hyperbolic model and exponential model that predict the ultimate bearing capacity of anchor rod have been contrasted and analyzed referring to the data of pull-out tests of anchor rod; it is shown that the exponential model is better suited for simulating the P-S curve of anchor rod and predicting ultimate bearing capacity of anchor rod.

Key words: anchor rod, ultimate bearing capacity, hyperbolic model, exponential model
