本发明涉及一种低成本高吸水复合保水剂及其制备方法。保水剂的原料的重量份数为：丙烯酸100份，凹凸棒土20-80份，膨润土20-80份，引发剂0.05-1.0份，交联剂0.05-1.0份。

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.
