摘要:

采用考虑起始水力梯度的非Darcy渗流方程,修正了Terzaghi饱和黏土一维固结理论,并用有限体积法进行了求解.计算结果表明,只要起始水力梯度大于0,地基的固结速度就慢于Terzaghi固结理论值,而且除固结系数外,起始水力梯度,土层厚度以及上覆压力也都对地基的固结有显著影响.另外,还证实,当主固结完成时,地基中存在一定的残余孔隙水压力无法完全消散.

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.
