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 simulation test, the average flow velocity of bedrock water with single flow path under different conditions was studied. The relationship between average velocity and hydraulic slope was calculated and the regression equation was established. To verify the average velocity equation of bedrock movement The new experimental basis, to solve the bedrock movement between the theory of the scope of the problem.
