摘　　要：分析了软土地基沉降量的组成部分,在此基础上探讨了软土地基沉降量的数值计算方法。提出目前用于软土地基沉降量计算的数值方法主要是差分法、有限元法和边界元法,其发展趋势是有限元法与差分法或与边界元法相结合解决课题,最后得出了一些有益的结论。Analysis and calculation of moving soft soil is a very important topic in road design. This article firstly analyses the combination of moving amount of soft soil, based on this, it discusses the mathematic calculation methods of moving amount of soft soil, brings forward the main methods in calculating are distinction methods, limit-unit methods and boundary unit methods. The developing trend is solving these topics by combination of distinction methods, limit-unit methods and boundary unit methods. Finally, it gets a favoring conclusion.
