Study on Adhesion Characteristics of Rubber–Soil Interface Based on Electric Double-Layer and Water Film Theories
Source abstract
Abstract
Soil adhesion is one of the basic physical properties of soil. The existence of soil adhesion will cause additional energy consumption of transport vehicles, which is an urgent scientific problem to be solved. In this paper, rubber tires are used as test materials, and the adhesion between rubber tires and different soils is measured by the improved adhesion test device. The rubber surface after the test is processed and analyzed by image analysis software. The results showed that the soil adhesion increased with the increase in soil moisture content and reached the maximum when it was close to the liquid limit. The maximum adhesion increased with the increase in soil clay content. The image processing analysis showed that the watermark area on the rubber surface will gradually increase with the increase in soil moisture content. According to the test results and the characteristics of soil colloid, the electric double-layer theory was introduced to establish the contact, adhesion, and separation model of the rubber–soil interface, and the adhesion mechanism of the rubber–soil interface was expounded. This study will promote the study of soil adhesion and provide a reference for estimating the additional energy consumption caused by adhesion during transportation.
