摘　　要：针对目前水库排沙清淤措施存在的优缺点,通过模型试验模拟了自吸式管道排沙系统和虹吸式管道排沙系统。管道排沙系统能够充分利用水库有效水头,利用布设在库区的管道把水库淤积的泥沙排出库外。通过模型试验,验证了两种排沙系统的排沙效果。试验表明:两种管道排沙系统的排沙效率较高,耗水少,具有较高的适应性和操作性。对水库排沙清淤措施提供了另一种思路,为管道排沙系统应用于水库排沙清淤提供了试验支持。Aiming at merit and demerit of sediment discharge and cleaning measures of reservoir at present,through model tests,the self-absorb pipe sediment discharge system and siphon pipe draining sediment system were simuated.Pipe sediment discharge system can fully use the effective water head of reservoir and discharged sediment through pipe.The effect of two sediment discharge systems were checked.Tests showed that two kinds of pipe sediment discharge systems had higher efficient,less water consumption and higher adaptability and operability.It provided another idea for discharge sediment measures and test support for application of pipe discharge sediment system into reservoir.
