Abstract

Soil adhesion is one of the basic physical properties of soil, which is manifested as the ability of soil to adhere to foreign objects. Soil adhesion can cause additional energy consumption in mechanical operations in agriculture, engineering, transportation and other fields, which is an important scientific problem to be studied and solved urgently. In this paper, three kinds of rubber tires with different surface roughness were used as test materials, and soil samples from six regions were selected as test soil samples. The adhesion force of rubber-soil interface under different normal loads was tested, and the variation law of soil peak adhesion force and the peak moisture content to reach peak adhesion force under the combined action of various influencing factors were analyzed and discussed. The mechanism of peak moisture content change under load was proposed. The test results show that the adhesion force of the rubber-soil interface increases with the increase of surface roughness, normal load and clay content. This experiment further promoted the study of soil adhesion and helped to solve the energy consumption problem caused by soil adhesion in the transportation field.
多因素影响下橡胶-土界面黏附规律研究
土壤附着力是土壤的基本物理性质之一,表现为土壤对外来物的粘附能力。在农业、工程、交通等领域的机械作业中,土壤黏附会造成额外的能源消耗,是一个亟待研究和解决的重要科学问题。本文以3种不同表面粗糙度的橡胶轮胎作为试验材料,选取6个地区的土样作为试验土样。测试了橡胶-土界面在不同法向载荷作用下的附着力,分析探讨了各种影响因素共同作用下,土壤峰值附着力和达到峰值附着力的峰值含水率的变化规律。提出了荷载作用下峰值含水率变化的机理。试验结果表明:橡胶-土界面的附着力随表面粗糙度、法向载荷和粘粒含量的增加而增大;本实验进一步推动了土壤附着力的研究,有助于解决运输领域土壤附着力带来的能源消耗问题。
