摘　　要：为了研究单裂隙中的高速水流运动规律,利用数值模拟建立了不同隙宽下光滑单裂隙中的水流运动。针对临界雷诺数为300~500,模拟了低速水流运动,模拟结果表明,运动规律与达西定律相吻合,从而验证了该数值模拟的可靠性;高速下,水力梯度与速度间开始偏离线性的达西定律。n order to study the law of high velocity water flow in single fracture, numerical simulation was used to establish the flow of water in aThis paper used numerical simulation method to simulate water flow movement in smooth single fissure of different width, with the purpose to study the movement law of high-speed water flow in single fissure. Low-speed water flow movement was simulated for 300-500 critical reynolds number. The simulation result showed that the movement law complies with Darcy＇s law, which verified the reliability of the numerical simulation; hydraulic gradient and speed started to deviate from the linear Darcy＇s law under high water flow speed.
