摘　　要：基于国内外接触冲刷的研究成果,分析了渗流接触冲刷的发生机理,比较了在无黏性土层、砂砾石层与黏土层接触面上发生接触冲刷的不同机理,总结了不同土层间接触冲刷的研究进展,并提出这一领域待研究的关键问题。Based on the domestic and foreign research achievements about contact scouring,the mechanism of seepage contact scouring is analyzed in this paper.The difference of contact scouring occurred at the interface of cohesionless soils and the interface between gravel and clay is compared.Studies on contact scouring occurred in different soils are discussed and summarized.The key points required for further research in this field are proposed.

关 键 词：接触冲刷 渗透破坏 渗透变形 接触面
