摘　　要：通过对软土路基在预压荷载作用下产生的附加压力的非线性计算与分析,提出在计算软土路基工程补方量时,应结合地基的路堤断面尺寸与填土荷载大小(即填土高度)等因素综合分析考虑,以得出预压加固软土地基的沉降补方系数。By nonlinear calculation and analysis of additional stress caused by pre-load in soft clay subgrade, various factors are considered and analyzed comprehensively, such as section size of subgrade, load （height） of filled clay, etc. And the compensated fill volume due to settlement for soft clay subgrade is obtained.

关 键 词：软土路基 补方量 附加应力
