- Abstract:
-
The non-Darcy seepage equation considering the initial hydraulic gradient is used to modify the one-dimensional consolidation theory of Terzaghi saturated clay and solved by finite volume method. The calculation results show that as long as the starting hydraulic gradient is greater than 0, the consolidation speed of the foundation is slower than the theoretical value of Terzaghi consolidation, and in addition to the consolidation coefficient, the initial hydraulic gradient, soil thickness and overlying pressure also have significant effects on the consolidation of the foundation. In addition, it is also confirmed that when the main consolidation is completed, there is a certain residual pore water pressure in the foundation that cannot be completely dissipated.
