摘要
钻孔振荡式渗透试验是一项成本低、简单、试验历时短、无需抽出或注入大量水的现场水文地质试验。近年来,振荡式渗透试验发展成为一项评价含水层渗透参数空间变化特征以及低渗透性岩土体渗透特性的重要水文地质试验技术方法。介绍其基本概念和原理、技术特点及发展,对比三种激发方式的优缺点,认为注水(抽水)式振荡试验更加方便快捷,并在深厚覆盖层和地下水位埋深较大的隧道工程勘察中进行了应用,取得了较好的效果。
Slug test in borehole is a site hydrogeological test that is low cost, simple, short duration, and without extracting or injecting large amounts of water. Recently, slug test is considered as an important technique to evaluate the spatial variations of aquifer seepage parameters and seepage characteristics of rock mass with low. The paper introduces the basic concept and principle of slug test, technical features and development, and compares the advantages and disadvantages of the three excitation modes that water injection（pumping） slug test more convenient. The method has been applied in thick overburden and groundwater depth larger tunnel engineering exploration, and has achieved good results.
