- Abstract:
-
The non-Darcy seepage equation considering the initial hydraulic gradient is used to generalize the one-dimensional consolidation theory of Terzaghi saturated clay to the condition that the ground load can be considered with time, and the numerical calculation format of the finite volume method is given. On this basis, the effects of the initial hydraulic gradient and construction speed on the consolidation characteristics of saturated clay layer are discussed. The calculation results show that the larger the initial hydraulic gradient, the slower the consolidation speed of the foundation, and the final consolidation degree is less than 1. The influence of construction speed is mainly reflected in the construction period and the early stage of completion.
