Abstract
This paper describes the results of a frost-heaving model test with anchorage in order to verify the frost-heave-proofing effect of a coned disk spring on the anchor head. The tests were carried out for changing restricted conditions without an anchor, and for changing initial working load condition of anchors with and without a coned disk spring on the anchor head. The following conclusions were obtained. 1) The anchor-working load and the displacement of an anchor plate at the time of frost heave have a hyperbolic relation. 2) A coned disk spring on an anchor head greatly decreased the working load during the frost heaving model test and also improved the anchorage frost heaving resistance. This paper also proposes a method for designing the coned disk spring on the anchor head.
