Abstract: The long-term settlement behavior of multi-story buildings on soft clay foundation in Shanghai is analyzed based on the long-term observed data of 50 multi-story buildings. Exponential model can reflect creep deformation of soft clay, which has obvious physical meaning of rheology. The long-term settlement of building is simulated well by analyzing the observed settlements after construction with the exponential model; and the final settlement and settlement duration are predicted. Considering the variation of thickness ratio (Ks) of very soft clay layers in the four types of subsoil, relationship between Ks and long-term settlement of building is obtained from analysis of all records. With the increase of Ks , the final settlement and settlement duration increase, while the ratio of settlement finished during construction is decreasing.

Key words: long-term settlement, multi-story building, soft clay, exponential mode
