Analysis on Influencing Factors of Compaction Test of Low Liquid Limit Silty Soil in Urumchi Area

Through study on compaction of low liquid silty soil in Urumchi area,this paper describes soil preparation method and the influence of moisture content and compaction work on dry density.It suggests that economical compaction work shall be determined based on difference situations.In this paper,the influence of the changes of residual soil height in compaction drum on compaction result is discussed.The last layer of soil shall be estimated at 4 mm during compaction to reduce test errors through correction of the influence of residual soil height.
