摘　　要：对有关问题进行讨论 ,指出传统的软土地基处理技术以保证上部结构施工和使用期的稳定性为主要目的。随着工程技术和经济建设的发展 ,对上部结构的要求提高 ,相应地软土地基处理的设计从控制稳定转向控制变形尤其是工后变形 ,由此产生的新一代软基处理技术在 2 1世纪将得到快速发展。To discussed some concerned problems and indicate as following:The primary purpose of conventional techniques for improving the soft soil ground is to ensure stability during structure and service.Along with development of engineering technique and social economics,requirement to upper structure are enhanced,and design of soft soil ground improvement has been changed from controlling stability to controlling deformation,especially post-construction deformation.New improvement techniques with small post-construction deformation would be developed rapidly in 21st century.
