中文摘要：岩石裂隙渗透性存在尺寸效应,但目前尺寸效应的控制机理还不甚明了。为探索岩石裂隙渗透性尺寸效应的规律及其控制机理,研制出了一套岩石裂隙渗透性尺寸效应试验仪。该仪器由供水装置、加载装置、集水装置、测量装置及大尺寸岩石裂隙试样组成,可以模拟不同定水头压力以及不同法向应力作用下岩石裂隙的渗流过程,而且可以获得水流经不同裂隙面尺寸时的渗透参数,进而揭示岩石裂隙渗透性尺寸效应的规律。可为进一步研究岩石裂隙渗透性尺寸效应规律及控制机理等提供可靠的试验装置。

外文摘要：Size effect exists in the permeability oi rock lracture, but the control mechamsm ot size effect is not clear, in order to explore the size effect of rock fracture permeability and its control mechanism, a set of rock fracture permeability size effect tester is developed. The instrument is composed of a water supply device, load- ing device, water collecting device, measuring device and large size rock sample, which can simulate seepage rock fracture force under different water pressure and different methods, and can obtain water through the permeability parameters of different fracture dimensions, and reveal the law of size effect of rock fissure permeability. It can provide a reliable experimental device for further studying the size effect law and control mechanism of rock fracture permeability.
