Taiyuan silt as the research object, by artificially changing the water content, and indoor simulated body vibration disturbed soil construction process, and then it，s done unconfined compression test measured the stress-strain values, analyze moisture content in the same disturbance conditions under the law of the soil thixotropic strength of the recovery. The results show: the external disturbance time is the same, the higher the moisture content of the soil by the greater degree of disturbance; standing time under the same conditions, the intensity of the degree of recovery of its water content was negatively correlated. Explores the relationship between soil moisture restoration of its extent and intensity of the disturbance between to provide a reference for the further study of soil moisture content is not the same physical properties studied.
