Abstract
This paper describes the results of shaking table model tests and FEM analyses of a slope with anchorage in order to verify the earthquake-proof effect of a coned disk spring on the anchor head. The model tests were carried out for the slope with and without a coned disk spring on the anchor head. The following conclusions were obtained. 1) The tensile force of the ground anchorage changes greatly with the shaking motions. 2) A coned disk spring on an anchor head greatly decreased the tensile force amplitudes during the shaking tests and also improved the earthquake resistance of the anchorage. In the tests, the tensile force amplitudes with a coned disk spring were one quarter to two thirds of the tensile force amplitude without a coned disk spring.
