    Abstract
  • The standard moisture absorption of soil is one of the important basis to judge the expansibility of soil. The relationship between the standard moisture absorption of soil and the composition of different particle sizes of soil were analyzed, and a certain linear function relationship between the standard moisture absorption of soil and the clay content (clay mineral content) was concluded. The foundation is established for the auxiliary judgment of the standard moisture content, and it is concluded that the standard moisture content is about 1/10 of the clay content numerically. At the same time, the mineral composition corresponding to different particle sizes of soil is analyzed, which provides the theoretical basis for determining the standard moisture content by clay content. By comparing with free expansion rate and plasticity index, the advantages of standard moisture content to judge soil expansion and particle composition to judge standard moisture content are analyzed.
