固结压力

By using Lee\'s matching law, the excess pore-air pressure, excess pore-water pressure and settlement in the Laplace-transformed domain are obtained for one-dimensional consolidation in unsaturated soils, under the large-area uniform instantaneous loading. A computer program using the method by Crump and Durbin is developed to obtain the semi-analytical solution of the excess pore-air pressure, excess pore-water pressure and settlement under the boundary conditions of the top surface permeable to water and air and the bottom impermeable to water and air.

At the latter consolidation stage, it was assumed that the water flow only depended on water pressure and was not influenced by the air. Then the independent continuity equation of water was set up to solve variation of water pressure with time. Besides, the water and air were regarded as mixed fluid, and the continuity equation of mixed fluid was set up.

在其后的固结过程中，假定水的流出仅仅取决于水压力，不受气的影响，单独建立水的连续性方程，解水压力随时间的变化；又将水和气看成混合的可压缩流体，建立混合流体的连续性，解混合流体压力随时间的变化。
