 The soil  of the Datun   Reservoir, Lingluo Reservoir and Guanlu Reservoir is typical dispersive soil. The dispersive grade needs to be determined for engineering safety. The double densimeter test, pinhole test and crumb test were developed on the dispersive soil. The dispersive grade was determined by the test results. The soil modification test by lime was developed and the filtration examination was done after modification. The results showed that the improvement effect  was the best with about 1.5% lime content. The filtration examination results showed that the engineer demand could be satisfied with the modified soil by lime, which could provide theoretical reference and technical support.
