在水工建筑中地质勘察阶段内,引用野外压水试验来进行建筑地区岩层单位吸水量(q)的测定方法,早已普遍的应用了。而且在水工设计方面也经常的向地质人员提出要求收集建筑地区、地下岩层的(主要指坚硬岩石)单位吸水量的数值,并且在设计上是完全根据岩层之单位吸水量 q 之值来进行防渗灌浆帷幕深度的确定。在国内几乎所有的设计人员,和一些地质人员都异口同声的采用了 q(?)0.01公升/分为设计防渗幕的临界线。在地质工作人员方面来说,很多人认为压水试验
In the hydraulic construction phase of geological prospecting, the use of field pressure test water in the construction area to determine the amount of water absorption unit (q), has long been widely used. In addition, in the aspect of hydraulic design, the quantity of water absorption of units (mainly hard rock) collected in the construction area and underground rock formations is also often put forward to the geologic staff and is designed based on the unit water absorption q of the rock formations Determination of impermeable grouting curtain depth. Almost all designers in China and some geologists use q (?) 0.01 l / min as the critical line for designing impermeable curtains. In terms of geospatial workforce, many people think of water pressure tests
