Because the scale of this kind of soil is not large, the embedding deepness and thickness is shallow, and the collapsibility is less or little, people don't regard the characteristics and collapsibility of this soil as important.

这种土一般分布在地表附近，具有一定的厚度，湿陷性相对较低，在地基勘查中往往将其视为一般粘性土处理，对黄土状土的特征、湿陷性等性质没有引起足够的重视，因而存在安全隐患。

Based on the balance of forces acting on interior earth fill of a counterfort structure, this paper proposes a theoretical calculation method of earth pressure on each member (including wall slab, counterfort and bottom slab) when the earth fill behind structure is in the condition of active critical equilibrium.

The PDMDAAC-bentonite is used to treat Reactive Turquoise Blue KN-G dye wastewater and Reactive Flavine K-4G wastewater respectively. The results show that the sorption behavior of KN-G and K-4G on the PDMDAAC-bentonite are in accord with Freundlich equation.

Then, the differential equations are solved by the Fourier expanding and Hankel integral transform method. Integral solutions of soil skeleton displacements and pore pressure as well as the total stresses for poroelastic media are obtained. Furthermore, a systematic study on Lamb's problems in transversely isotropic saturated half-space is performed. Integral solutions for surface radial, vertical and tangentical displacements are obtained both in the case of drained surface and in the case of undrained surface excited by vertical and tangentical harmonic resources respectively. Numerical results show the obvious difference between the model of isotropic saturated poroelastic media and that of transversely isotropic saturated poroelastic media.

其次，基于Biot波动理论，在圆柱坐标系下求解了横观各向同性饱和土的Biot波动方程：通过引入位移函数，在圆柱坐标系下将横观各向同性饱和土的Biot波动方程转化为两个解耦的6阶和2阶控制方程，然后根据方位角的Fourier展开和径向Hankel变换，求解波动方程，得到以土骨架位移和孔隙水压力为基本未知量的积分形式一般解，并用一般解给出了饱和土总应力分量的表达式；再以基本解为基础，系统地研究了横观各向同性饱和半空间体的Lamb问题，考虑表面排水或不排水两种情况后，首次得到横观各向同性饱和半空间体在表面竖向和水平谐振力作用的下径向、竖向和周向位移的解析解。

The result show, pH of solution, the type and concentration of surface-active agent all have marked effect, pH change can transform the disperse behavior of attapulgite particle by altering granularity distributing in different range, influencing double electromotive force between particle and solution.

研究表明，水溶液的pH值、表面活性剂的类型和浓度对凹土的分散稳定性皆有显著的影响，pH值的变化改变了不同粒径范围的粒子总量分布，改变粒子与溶液间双电层电动势，从而改变凹土粒子的分散行为：由于凹土作为带电粒子在极性溶剂中容易达到物理分散的目的，因此，凹土在极性溶剂中的分散状况大大优于在非极性溶剂中的分散。

The sodium bentonite was modified by organic reagent hexadecyl trimenthyl ammonium bromide and cationic polyacrylamide. The structures of modified organo-bentonite and the effect of concentration of the intercalating reagent and reacting time on decoloring capacity were studied.
