The single borehole multiple anchor cables have been widely used in the fields such as slope protection and landslide remedial projects in these years. Based on the in-situ pull-out test of anchor cables in a landslide

this paper pays attention to how to test both the stress of anchorage segments and the loss of prestressing force. Accordingly

a new method is put forward and introduced in detail; the basic principle of the method is mainly accomplished by testing the stress of individual steel strands of anchor cables

whose feasibility is demonstrated in the engineering practice. Finally

the forces of individual steel strands which are located in different position along the borehole are successfully tested; the results provide direct proofs for the anchor cables design and construction in the condition of in-situ engineering geology

and have practical engineering applicative values.
