The strength characteristic in the earthquake of Air Mortar has not been sufficiently clarified until now. So we carried out the static horizontal loading tests and shaking table tests. The followings were obtained from the present study; 1) Shear strength was evaluated by two parameters, i.e., upper load pressure and compressive strength; 2) The Air Mortar embankment breaks by shear in the earthquake, so it has to have enough shear strength.
