Abstract
The seismic coefficient method used for an earthquake-proof design method of gravity retaining wall is not clear to be actually the safety side method. Because it covers the unknown field of phenomenon by various safety side setups but it also contains dangerous side setups. Then, it is necessary to make clear the seismic behavior of the gravity retaining wall and take it into the design to make the design method be rational. So conducted centrifugal model tests of gravity retaining wall. Data analysis showed that the present design method is able to be rationalized by calculating the seismic earth pressure by the active earth pressure of static state, setting the seismic coefficient to be 0.4, etc.
