抄録: To construct the main tower foundation of suspension bridge (the Swan Bridge), the method using an artifical island and a continuous underground deep wall was applied. Since the firm bed rock is found to lie 103 m below the sea level and the continuous underground deep wall becomes a tall structure with 106 m height, it is very important to study the stability of the structure for earthquake. In this paper, the dynamic stabilities of the continuous underground deep wall for earthquake at five stages of its construction are numerically discussed. Numerical analyses are executed considering the interaction among the continuous underground deep wall, an artificial island and its surrounding ground, by means of finite ring element method. An artificial earthquake wave made for the design of the bridge is inputted on base rock. From this study, both dynamic bending stresses in the continuous underground deep wall generated according to the beam and plate actions can numerically estimated.
