摘　　要：采用碎石换填法处理软土地基,最需注意的问题就是其在压实荷载作用下的沉降。道路路基的设计中主要以控制沉降变形为目标,分析了碎石垫层法处理软土地基的沉降计算方法,有关经验可供相关专业人员参考。The macadam replacement method is used to treat the soft soil subgrade. The issue for attention is its settlement under the action of compaction load. For the objective mainly to control settlement and deformation in the design of highway roadbed, the article analyzes the settlement calculation method of macadam cushion to treatment soft soil subgrade. The relative experience can be referred for the similar projects.
