Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.

然后，在充分考虑竖井区井阻、涂抹作用以及土体结构损伤破坏对固结影响的基础上，将未打穿竖井地基合理地转化为双层地基，按一维固结理论计算，克服了传统固结计算方法在竖井处理区与下卧层交界面处存在孔压间断的缺点；在此基础上，从超载预压法的基本原理出发，分析了双层地基超载预压固结、沉降机理，推导了多级等速加、卸载情况下双层地基的固结计算公式，进一步完善了双层地基固结理论。
