摘　　要：对堆载预压和真空预压加固中软土地基固结沉降计算值的合理修正方法作了分析和探讨。影响加固土体固结沉降的主要因素是体积应变和侧向位移，用本文提出的可计算的体变修正系数msv和侧移修正系数msl进行沉降修正要比按单一综合系数ms取值修正更实用和切合实际。A reasonable method to modify the calculated settlement of soft clayey foundation in superload and vacuum preloading consolidation is analyzed and discussed in this paper. The main factors affecting settlement of consolidated foundation are volume deformation and lateral displacement. With two calculable coefficients msv and msl，which is suggested in this paper, to modify the settlement will be more useful and practicable than with a general adopted coefficient ms.
