—、导言 随着祖国大规模经济建设的开展,水文地质及工程地质勘测工作也达到了空前的发展。在勘测工作中用来测定原状疏松土的渗透系数的渗透仪制造也日益增多。据作者所知,目前,地质部所属各地质院校的实验室都已购置了渗透仪,但这些仪器都只能装置在实验室里使用,这样不但造价高昂而且在实验室中也占据了很大一部分面积,而在野外作水文地质调 -, Introduction With the development of large-scale economic development in the motherland, hydrogeology and engineering geological survey have reached an unprecedented development. Permeability meters used to measure the permeability coefficient of undisturbed soils are also increasingly being manufactured during the survey. According to the author’s knowledge, at present, all the laboratories in geology colleges and universities affiliated with the Department of Geology have purchased permeameters, but these instruments can only be used in laboratories, which is not only expensive but also occupy a very large amount in laboratories Large part of the area, while in the wild for hydrological geology
