【摘要】 岩溶区，地下管道中的水流不符合渗透定律，当岩溶管道被地下水充满形成承压管流系统，在性质上类似有压管路水流，因而应当采用水力学的原理对岩溶水运动进行描述。本文推出了有裂隙水均匀入渗时地下河管道沿程水头损失计算公式，并提出了岩溶管道等效直径的计算方法。用水力学模型对管道系统计算等效直径及预测管道水头损失值，与实测值基本一致，这些结果是可以接受的。研究成果表明，应用水力学原理解决岩溶管流区地下水运动问题具有良好的前景。更多还原

【Abstract】 In karst area,the water movement in the karst channel system is not consistent with Darcy’s law,the pressurized channel system in formed when the karst channel system filled water,the water movement is approximatly to pressurized channel flow so that hydraulic theory can be used to describe the movement of karst ground water.In the thesis,the author put a calculative equation for water head lose,in which water flow in fractures infiltrated homogeneously in karst channel of subterranean river and posed the calculative method of the eguivalent radius in karst channel.The radius of karst channel can be calculated by hydraulic model,based on this calculative radius,the water head lose on some point can be calculated,too which forecasts that water head Lose is identify with the practical survey value.This calculative value may be acceptable.Hydraulic theory is useful in solving problems about ground water movement in karst areas.更多还原
