The dike, a structure used to establish an impounding area, plays importanto roles for the safety of LNG storage refrigeratded to -162Ž, which structure should function even if extreme loading conditions arise. The three large posttensioned cylindrical concrete dike have been built for 80 000kl LNG tanks at Himeji, Japan. Each dikes has the dimension of 91m in diameter with 14m in effective storage depth. The post tensioned concrete dike is advantageous on structural strength, liquidtightness and economical construction of cryogenic structure in a highly seismic region. The paper covers the overall aspects of design and constuction of the dikes. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF ˜_•¶ ‹æ•ª @@@@˜_•¶W
