| Abstract: | The equivalent one-dimensional consolidation coefficient method is used to deal with the radial seepage of the drainage plate, and the consolidation control equation is obtained by combining the existing nonlinear rheological time line model. The semi-analytical method is adopted to solve the consolidation control equation following the time-space discretization. The solution is utilized to calculate the consolidation settlement of the foundation of a new airport in Xiamen. Compared with the field-work results, the settlement development trend is well predicted, which can be extended to other projects alike. |
