| 摘 要： | 借鉴多孔介质非饱和渗流试验的研究成果,研制出一套可同时测定单裂隙毛细压力-饱和度以及非饱和渗透系数-毛细压力关系的试验装置.为检验试验装置的可信度和试验原理的正确性,并初步探讨单裂隙非饱和渗流的机理,特制作了一阶梯开度的裂隙概化模型(本文称之为“S-H”裂隙模型),并在上述试验装置上进行了“S-H”裂隙模型的非饱和渗流试验,初步阐明了单裂隙非饱和渗流的一些基本水力特性,同时试验结果也表明本文试验装置和试验原理合理可靠.

| Abstract: | A test method of unsaturated seepage flow of single fracture is presented and an experimental equipment for testing the relationship of capilary pressure,saturat ion and unsaturated permeability of fracture is developed. In order to examine the reliability of experimental provision and the validity of experimental principle,and to expound the mechanisms of unsaturated seepage flow in fracture,a simplified fracture model with flight aperture is developed and an experiment of unsaturated seepage flow in this fracture model is done Mechanisms of unsaturated seepage flow in fracture are expounded initially.At the same time,the experimental results show that the experimental provision and the experimental principle in this paper are reasonable and reliable. |
