摘　　要：水在破裂岩石的渗流不服从Darcy定律。由于破裂岩石的渗透率很大和密封方面的困难,在MTS试验系统上采用瞬态渗透法不能测量破裂岩石的渗透率。为了研究破裂岩石的非Darcy流渗透特性(渗透率和非Darcy流β因子),开发了一种破裂岩石非Darcy流渗透特性试验附加装置。本文介绍了这种附加装置的构成以及其嫁接到MTS815.02系统上测试非Darcy流渗透特性的试验原理和试验技术要求,并给出了试验系统的应用。The seepage flow of water in fractured rock doesn't obey Darcian law. Owing to the magnitude of permeability and the difficulties in seel, the permeability of fractured rock can't measured in MTS815.02 Rock Mechanics Test System by transient penetrating method. To investigate the non Darcian penetrating properties(permeability, k andβfactor of non Darcian seepage flow,β), an accessional device, which attaches MTS815.02, is designed. In the current article, the configuration of the accessional device is introduced. The principle and test skill of measurement of penetrating properties is stated. Application of test system of penetrating properties of non Darcian flow is given.
