In this paper the authors focus on design method of caisson foundation during large-size earthquakes. To define behavior and supporting mechanism of caisson foundation, model lateral loading tests covering large-displacement are performed and analyzed. As a result, it is found that the simple calculation method of caisson foundation which assume elasto-plastic property of coefficients of subgrade reaction can precisely simulate the envelope curves of load-displacement curves of the test results to large-displacement. It is discussed that the possibility of application of design method of caisson foundation by equivalent energy method. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
