A testing method and apparatus for ground liquefaction and dynamic characteristics in the original position utilizing a boring hole, wherein the dynamic strength and deformation characteristics of a soil layer against a dynamic repetitive load, in an optional position in the ground can be obtained by a simple method. A measuring cell based on a three-chamber construction is used, and upper and lower soil layers (J 1 , J 3 ) with an intermediate soil layer (J 2 ) therebetween are alternately subjected to a dynamic repetitive load, and what influence there is on the intermediate soil layer (J 2 ) is investigated from the relation between pressure and displacement.
