| 摘 要： | 裂隙岩体中的流体流动和物质传输主要发生在裂隙空间中，但由于裂隙结构的非均质性和应力作用的影响，裂隙介质的细观流动特性表现出较强的复杂性。本文通过扫描真实裂隙结构面获取裂隙细观结构，采用格子Ｂｏｌｔｚｍａｎｎ方法模拟岩石裂隙中细观流动过程，研究粗糙裂隙在剪切条件下细观流动特征，揭示剪切错动裂隙在流速增大过程中涡流的形成和演化过程及涡流造成裂隙有效对流区减小、过流能力降低的细观机制。

| Abstract: | Rock fractures constitute the main space of fluid flow and material transport. However, due to the influence of heterogeneity and external force on fracture structure, the micro-characteristics and macro-laws of fluid flow in rock fractures have strong complexity. Based on microscopic structure obtained by scanning a real fracture, lattice Boltzmann method was used to simulate the meso-flow process in rock fractures, and the characteristics of fluid flow in rough fracture under shear conditions were studied. |

| Keywords: | rough fracture flow characteristic lattice Boltzmann method shear process |
