岩体单裂隙渗流特性研究综述

Research review on single fracture seepage characteristics in rock masses

为了提供一个关于岩体裂隙几何特征对其渗流特性影响的全面综述,大量调研多年来国内外学者所开展的相关研究工作,总结出开度、粗糙度和应力条件等因素对单裂隙渗流特性的具体影响。结果表明:在开度、粗糙度、应力条件等3种对单裂隙渗流产生影响的因素中,开度影响最早被研究,针对粗糙度影响效应的研究开展较晚,有关应力的研究在近30 a中逐渐增多且愈发被重视。此外,总结出试样制备、开度值获取以及粗糙度表征等未被考虑、提出和解决的关键的问题。研究成果可为岩体裂隙渗流特性的研究提供借鉴。

In order to provide a comprehensive overview of the influence of geometric characteristics of rock fractures on their seepage characteristics,extensive researches conducted by scholars both domestically and internationally over the years had been reviewed.The specific effects of factors such as aperture,roughness,and stress conditions on the seepage characteristics of single fractures were summarized.The results showed that among the three factors affecting the seepage characteristics of single fractures,aperture was the first to be studied.Research on the effects of roughness started later and the studies on stress had gradually increased in importance over the past 30 years.Additionally,key issues related to sample preparation,aperture measurement,and roughness characterization that had not been considered,addressed,or solved were identified.The findings of this research can provide valuable insights for the study of seepage characteristics of rock fractures.
