In this study, traveling tests of a rigid wheel were carried out on sandy ground, and displacements of soil particles were measured with a constant interval using the on-line displacement measuring system. Trajectories of a soil particle drew a circular arc in any test. Magnitude of the displacement increment vectors, its horizontal and vertical components were discussed, and characteristics of those were clarified. Shapes of these distribution curves were closely similar to the Gaussian function. Based on the results, mathematical models for the horizontal and the vertical displacement increments were proposed employing the Gaussian function as a base function. The predicted curves by the models agreed with high accuracy to the measured curves.
