Rheological properties of pressure-type anchors are studied by the pulling-out test of anchorage system in laboratory. The anchorage system is well designed and produced. The test data is reliable and is in line with scientific laws. By designing with the different fixed anchor lengths and mortar strengths, the test studies that the displacements change over time along the axial direction under different load. Compare deeply the different strength of mortar and the different anchorage length on the anchoring effect. It concluded that the fracture of the grouting body whose length is 300 mm reinforcement, the destruction of the specimen whose grouting body's length is less than 300 mm is on the second interface of anchorage;when the concrete strength is small, if the radial stress increases to a certain value, the matrix was to crack in the first.
