摘　　要：采用窄缝槽物理模型来模拟地下水运动,具有形象、直观的优点。其基本原理是利用层流状态下液体在窄缝槽中运动时的特征、规律与坝下渗流相似的特点。绕坝渗流仪的研制成功,为解决坝下渗漏问题提供了理论依据;同时对运用窄缝槽渗流理论研制其它类型地下水运动规律的相关物理模型,以解决地下水运动中的实际问题,具有重要参考价值。The physical model of narrow slit has been adopted to simulate groundwater movement and it has many excellences in visualization and intuition. Its fundamental is to utilize the character and law of liquid movement in narrow slit under laminar flow and the specialty of seepage similitude below a dam. The success about the research and development of seepage instrument around dam can provide theoretical basis for solving leakage problems below a dam. Meanwhile, it shows important referenced merit to apply seepage theory of narrow slit as the related physical model which finds out the law of other groundwater movement so as to solve the practical problems of groundwater movement.
