采用分离变量法,求解了任意荷载作用下渗透系数和体积压缩系数随深度按幂函数变化土层模型的一维固结问题,从而得到不同排水边界条件下超孔隙水压力和沉降等随时间变化的解析表达式.通过计算分析,讨论了该类非均质土固结时超孔隙水压力、沉降的变化规律.
The discrete variables method was used to solve the one-dimensional consolidation problems of the soil model with permeability and volumetric compressive coefficient varying with depth as a function of depth under arbitrary load. Thus the excess pore water pressure and settlement under different drainage conditions were obtained. The analytical expressions of excess pore water pressure and settlement during the consolidation of such heterogeneous soils are discussed.
