摘　　要：叙述了道路设计中软土的分布、物理性质、界定标准、软土路基的危害,介绍了常见软土路基的处理方法、适用条件及选用原则。结合工程实例,阐述了软土路基处理方法的选择过程、施工监测及效果检验方法,提出了现行国家规范在工后沉降标准要求上的不足和道路设计中软土路基处理应遵循的原则。This paper described the distribution of soft soil, physical properties, defining the standard, the harm of soft soil subgrade in road design, then introduced the treatment method, application conditions and selection principle of soft soil subgrade. Combined with engineering examples and geology, the selection process of soft soil subgrade treatment method is described, and the construction monitoring and effect test method of soft soil subgrade is also briefly described.At last, the paper put forward the deficiency of the current national norm in the post-industrial settlement standard and the principle of the road design.
