摘要： 为了解决渗流作用下土-结构接触面变形条件难判定的问题,本研究设计了土-结构接触面渗流变形试验装置,研究渗流作用下接触面变形、土体表面变形、土体内部变形分布规律以及随水力坡降增加的演化规律,分析了不同接触面和土质对接触面渗流破坏的影响机制。结果表明:(1)试验中接触面水平方向的变形呈对称分布,垂直于接触面方向上的土体内部变形随距离增加呈现非线性减小的趋势;(2)土-结构接触面渗流破坏过程分为稳定、过渡和破坏3个阶段,接触面变形、接触面渗透系数在3个阶段分别呈现线性增大、非线性增大和激增的趋势;(3)砂土-结构接触面渗流破坏时的应变普遍为9.0%左右,粉土-结构接触面渗流破坏时的应变为7.9%~9.1%,低液限黏土-结构接触面渗流破坏时的应变为5.2%~6.5%。

Abstract: In order to solve the problem that it was difficult to determine the deformation condition of the soil-structure interface under seepage, an experimental device for studying seepage-induced deformation at this interface was designed. This study investigated the distribution characteristics of interface deformation, soil surface deformation, and internal soil deformation, as well as their evolution with increasing hydraulic gradient under seepage action. The influence mechanism of different interface types and soil types on interface seepage failure was analyzed. The main conclusions were as follows:(1)the horizontal deformation of the contact surface was symmetrical in the test, the internal deformation of soil in the direction perpendicular to the contact surface showed a nonlinear decreasing trend with the increase of distance;(2)The seepage failure process of soil structure interface could be divided into three stages, stability, transition and failure, the deformation of the contact surface and the permeability coefficient of the contact surface showed the trend of linear increase, nonlinear increase and sharp increase in the three stages respectively;(3)The strains at the sand-structure interface were generally about 9.0%, strains at the silt-structure interface ranged from 7.9% to 9.1%, while strains at the low-liquid-limit clay-structure interface ranged from 5.2% to 6.5%.

Key words: seepage, soil-structure contact surface, deformation, evolution law, hydraulic gradient
