对成层土的一维固结理论进行了重新研究。采用有限元法求解了耦合（沉降和超静孔隙压力）、非耦合（仅超静孔隙压力）和经典太沙基方程。由于只考虑固结系数（cv）的变化，经典太沙基方法无法满足层间界面处的流动连续性条件。
One-dimensional consolidation theories for layered soil have been re-examined. Coupled (settlement and excess pore pressure), uncoupled (excess pore pressure only) and the classical Terzaghi equation are solved by the finite-element method. By accounting only for changes in the coefficient of consolidation (cv), the classical Terzaghi approach is unable to satisfy the flow continuity conditions at the interface between layers.
