Abstract:
This paper int roduces sysmet ically the numerical calculat ion of vacuum-heaped load precompression in the consolidat ion of sof t clay w ith FEM, based on the Biot theory on three-dimensional consolidat ion. The numerical analysis and calculation of the chang ing procession of displacement , stress-strain, pore-space water press in a project about consolidated motorw ay states that the method has high precision.
