Experimental Research on Vibrating Compaction Characteristics of River Sand

Abstract:

River sand was used for filling embankment in highway for saving land resources and protecting farmland. In order to explore vibrating compaction characteristics of river sand, the effect of vibrating frequency, vibrating time, and moisture content on the indexes of dry density and modulus were investigated using orthogonal test design. The results indicate that the dry density values increase with the increase of three factors (vibrating frequency, vibrating time, and moisture content), while the modulus values increase with the increase of frequency and vibrating time, but decrease first then increase with the increase of moisture content. Vibrating frequency has a significant effect on dry density, but both vibrating time and moisture content have no significant effect, while three factors all have no significant effect on modulus.
