摘　　要：利用扫描电镜观察了土壤/橡胶粘附系统自然风干后界面处土壤表层微形态,发现土壤表层呈现各种尺度的粗糙结构,微观形态特征与界面所受法向压力的大小有关。文中还对土壤与固体外物表面粘附的机理进行了分析,并依据粘附界面土壤固相形成特征,探讨了土壤粘附界面水膜状态及其对土壤粘附强度的影响。Soil micromorphology at the rubber/soil adhesion interface after natural drying of the adhesion system was observed with scanning electron microscope. It was found that there exists rough structure with various sizes, the micromorphology has reiationship with the normal pressure applied on the adhesion interface, and high nor- mal pressure can result in closed ceils at the interface. The rubber/soil adhesion mechanism is analyzed. The in- terfacial pressure can result in closed ceils at the interface. The rubber/soil adhesion mechanism is analyzed. The in- terfacial water film plays important part in the soil adhesion.
