Abstract The creep equation of simulated material of soft rocks is given through model testing research on soft rocks reinforced by prestressed anchor cable. The characteristics of prestress of anchor cable varied with time are discussed in particular. Then the relationship between the initial prestress and the stable prestress in anchor cable is analyzed. Based on above results，an estimating method of pulling force of anchor cable decreased with time is finally proposed.
