| Abstract: | According to the obviously rheological characteristics during the construction of soft clay foundation engineering in wuxi, the foundation deformationt of wuxi library and its viscoelastic model were studied by employing viscoelastic theory and back analysis method. Comparing the observed data with the computed data, the viscoelastic parameters were modified. Based on the modified viscoelastic parameters the ultimate foundation settlement was predicted and coincided with the fact perfectly. Then an effective method and thoughts for the ultimate soft clay foundation settlement in wuxi was given. |
