摘要
介绍一种渗流条件下人工液化冲沙试验装置,该装置采用微型变态模型和不同的模型比尺,利用人工垂向液化技术降低泥沙的启动应力和启动流速的原理,在低流速、小流量的情况下实现高效冲沙,节约冲沙用水,为水利工程的高效排沙提供一种依据,尚需对不同的工程进行更进一步的试验,研究出可供工程采用的压力渗管装置,并在工程中实施。
One test device for sand flushing through artificial liquefaction under seepage condition is introduced.This device applies micro distorted models and different scaled models.By utilization of the principle for reducing the initial stress and initial velocity of sediment through the artificial liquefaction technology, sand is flushed at high efficiency in conditions of lower velocity and discharge.This saves sand-flushing water and provides the high-efficiency sand flushing of water resources projects with concrete basis.Further tests on differ-ent projects are required so as to find the pressure seepage pipe device which can be applied and used in engineering practice.
