摘　　要：根据模拟试验，研究了不同条件下小隙单一流径基岩水的平均流速；对平均流速与水力坡度间的关系进行了统计，建立了回归方程；为验证基岩水壁间运动的平均流速方程提供了的新的实验根据，解决了基岩水壁间运动理论的适用范围问题。According to the data obtained from simulated tests in laboratory,the s studies the average velocity of bedrock water flow in a single fracture within 3mm width in different condition,and establishes statistics equations of the average velocity and hydraulic gradient.A new test proof has been provided for testing the average velocity equations about bedrock water flow in the void between surfaces of rock's continuity interrupted.And the application scope of the theory about bedrock water flow in the void has been enlarged.
