新型多功能渗透仪与达西定律实验教学

A Newly Developed Multi-function Permeameter and Permeability Tests

地下工程实践活动中,渗流问题普遍存在。开展室内渗透(达西)实验教学对于学生熟悉渗流的基本原理,掌握地下水稳定流、非稳定流定量分析理论具有至关重要的意义。常规达西定律实验装置可以获取单一均质介质的渗透系数。作者研制了一套多功能渗透试验仪,能更好地模拟自然界中双层或多层结构含水层中的渗流;提供学生在实验中根据不同的渗透介质、渗流方向和实验方法,自行设计、选择不同的组合方案开展实验工作的机会。

Groundwater seepage exists throughout all the process of construction and operation of underground projects.Traditional permeameter only can measure permeability in single layer.A newly developed multi-function permeameter was introduced,which can measure permeability of double-layered geo-material directly.With the multi-function permea-meter,students can choose the test procedures by themselves according to the geo-materials tested and technique they like.
