When a clay layer is subjected to cyclic shear, the excess pore water pressure is accumulated in the clay and after the earthquake, it dissipates with time and then ground subsidence occurs. In this paper, to predict the rate of post-earthquake ground settlement, cyclic simple shear tests under the constant volume conditions are performed for a saturated kaolinite clay. After the cyclic shear tests, the excess pore water pressures are dissipated and the coefficients of consolidation are observed. Test results are used in the calculations of the rate of post-earthquake settlement of the model ground. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
