前言通常把流土、管涌、接触冲刷与接触流土、土发生渗透破坏的现象,总称为土的渗透变形。关于土的渗透变形形式的分析与临界水力坡降的计算问题,国内外已作了一些研究,取得了一些成果。本文将通过几个工程中曾经发生过的渗透变形形式及采取的渗流控制措施的情况, Foreword Usually flow, piping, contact erosion and contact flow, the phenomenon of soil infiltration and destruction, collectively referred to as soil infiltration deformation. With regard to the analysis of infiltration deformation of soil and the calculation of critical hydraulic gradient, some researches have been made at home and abroad and some achievements have been made. This article will be through several projects have occurred in the infiltration deformation and take the case of seepage control measures,
