摘　　要：在软基上填筑路堤或进行堆载预压时主要关心的是稳定问题和固结沉降问题。稳定分析常用的计算方法是圆弧滑动法和地基承载力法 ;对沉降计算常用侧限压缩模量。也有考虑土的本构关系 ,用其变形模量进行计算的简化方法。对这些常用的方法进行了探讨 ,开发了相应的计算软件。通过对某工程实例进行计算 。The two main concerns in preloading on soft foundation are stability analysis,consolidation analysis,and settlement calculation.Circular slide method and bearing capability method are two frequently used methods in stability analysis.Oedometric modulus is generally used in settlement calculation.And there is also simplified method using modulus of deformation by considering constitutive model of soil to calculate settlement.The authors discussed these methods and developed a design software.By calculating a preactical engineering,the results by different methods are compared.
