In this paper, a method of settlement analysis for buildings with mat foundation is described by considering the rebound of the ground. Generally the ground rebound and the settlement are caused by the excavation and the weight of structure, respectively. To estimate them, it is necessary to take hold of the variation of the excess pore water pressure in the clay layer by the time elapsed and to analyze the interaction between the ground and structure. We presented the relative expression between the mean consolidated pressure, and the coefficient of volume compressibility mv and the coefficient of consolidation cv based on the results of the cyclic consolidation test. And we calculated the rebound and the settlement of the building with basement by the excess pore water pressure obtained from mv and cv. By these results, we obtained that the properties of the ground settlement were changed from excavation period and starting time of the construction of the building and effected largely by the rebound of the ground.
