对昆明盆地浅层软土的形成环境条件、成因类型及分布规律进行了分析 .在此基础上 ,结合该软土的工程地质性质 ,提出了相适应的工程地质分类原则和方法 ,并划分出相应的工程地质类型 ,希望以此带动我省岩土工程界对此类问题的综合研究 . The forming environmental conditions, genetic types and distribution rules of shallow soft soil in Kunming Basin are analyzed.On the basis of this, combined with the engineering geological properties of the soft soil, the corresponding engineering geological classification principles and methods are proposed and divided into The corresponding engineering geological types, hoping to promote the geotechnical engineering in our province on such issues a comprehensive study.
