Analytical solution for one-dimensional consolidation of structured aquitard soils in second kind of leakage system

Considering the behaviors of structured aquitard soils, the analytical solutions expressed by water head for one-dimensional consolidation of structured aquitard soils in the second kind of leakage system are deduced by transforming the structured soils into the double-layered ones with gradually changing thickness. The solutions are given in the case of instantaneous and linear decline of confined aquifer water level respectively. By comparing three different examples, the effects of the structured behaviors on the consolidation characteristics are analyzed in the case of instantaneous decline of confined aquifer water level. The results illustrate that the more conspicuously the structural behaviors perform, the slower the changing rate of the water level is, and that it takes longer time for the water level to achieve stable state, consequently, the increase rate for the average degree of consolidation in terms of deformation becomes slower.
