摘要
本文推导了非饱和土三维固结控制方程组，它由三个静力平衡方程、一个连续性方程和一个吸力状态方程组成，包含五个基本未知量（三个位移分量、一个孔隙水应力和一个孔隙气应力）．这是不同于前人思路的一种尝试，饱和度可用其它基本未知量表达，不作为独立变量而只作为方程中的可变参数出现．饱和土的Ｂｉｏｔ固结方程可作为该方程组的一个特例而存在．文中还就方程组求解、本构模型和参数测定等问题提出了一些设想．
In this paper,a govering equations are derived which include three equilibrium equations,acontinue equation and a suction equation with five variables. It is an attemptthat saturate degree is not as a variable and different from prevenient equations mentioned by others.Blot consolidation equations for saturated soils is a special case of thegovering equations of this paper.In addition,some problems for constitutive model and measurement of the parameters are discussed.
