摘    要:基于宽配曲线,首次提出频率隙宽的概念,它具有表征隙宽分布情况、均匀程度、充分体现隙宽组成等重要意义。特别是频率水力隙宽的提出,为解决现有水力隙宽应用中出现的局限性具有极大的帮助作用。借助现有研究成果,通过实例分析得到,水力隙宽eh基本与中值隙宽e50相应,再通过随机裂隙的计算机有限元模拟,频率水力隙宽可取e48。

关 键 词:岩体  频率水力隙宽  地下水渗流  裂隙渗流

Abstract:The frequency aperture given in this paper is a new method that describes the fracture aperture composition. The aperture curve plays a role in describing the aperture distribution and uniformity. In particular, the frequency hydraulic aperture is of great importance in seepage analysis. It overcomes limitations of hydraulic aperture and mean aperture. Based on existing information, the result of example calculation shows that the hydraulic aperture e h equals to the median aperture e 50 . This paper also obtains that the frequency hydraulic aperture e sh equals to e 48 through finite element numerical modeling for various type of random fracture.
Keywords:aperture curve  frequency hydraulic aperture  median aperture  random fracture
