It points out that it must use unsaturated soil theory to consider the stabilization of construction established on loess and dilative soil subgrade. It uses single-phase flow theory and neglects the effect of porous air to describe the flow in unsaturated soil. The saturation of water and pore water pressure are taken as state variables, the effective stress and water flow velocity are expressed using these variables.

对于非饱和渗流孔隙水压力-位移耦合分析问题，本文采用单相流理论，忽略孔隙气压力的变化及其对土体变形的影响，以孔隙水饱和度和孔隙水压力作为状态变量，给出了非饱和土的应力状态表达式、渗流特性，建立了非饱和流孔隙水压力-位移耦合分析的有限元程式。
