摘要

摘要: 在第二类越流系统中,考虑弱透水土层的结构性,将单层土转化为土体厚度不断变化的双层土一维固结问题,推导了以水头表示的结构性弱透水土层的一维固结解析解,进而给出了水位瞬时和线性下降情况的解答。结合3种不同算例,分析了在水位瞬时下降情况中,土的结构性对固结性状的影响。结果表明：结构特性越强,水头变化越慢,趋于稳定的时间越长,按沉降定义的平均固结度在结构性强的土层中增加得越缓慢。

Abstract: 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.
