摘要：

As a new-type of soil anchor, the fiber reinforced plastics (FRP) screw anchor has a lot of attractive properties, such as high strength, light weight, convenient installation, light pollution, high corrosion-resistance and low cost. The basic structure of FRP screw anchor and their field pull-out tests were introduced, and the test results of un-grouted and grouted anchors were presented. The maximum pull out force of the grouted anchors was about 15-20 kN with less pull out displacement compared with that of un-grouted anchors, whose pull out force was about 10 kN. The pull out forces of both grouted and un-grouted anchors were compared with those obtained from design formulas. Finally, some ideas were put forward to improve the design and construction of FRP screw anchors.
