在工程地质勘察中利用钻孔水压试验,求得建筑地区岩层吸水性及其间的裂隙发育情况和性质,作为防渗幕下置深度的依据,现已被普遍运用,近年来随着祖国工程地质事业的发展,水压试验工作中的试验器材或操作方法均有所改进。现将笔者在实际工作中的一些体会提供讨论,不妥之处,希批评指正。 In the engineering geological survey using borehole hydraulic pressure test, obtained in the construction area of ​​rock strata water absorption and fracture development and nature, as the basis for the depth of the impermeable curtain has been widely used in recent years as the motherland engineering geology Development of the business, hydraulic test work in the test equipment or methods of operation have been improved. Now the author in the actual work of some of the experience to provide discussion, inappropriate, hope criticism correct.
