淤地坝淤粗排细作用研究初探

Primary Research about Silt Thick Platoon Thin in Silt Dam

通过对韭园沟小流域不同工程结构的淤地坝进行泥沙淤积规律研究,从而揭示了淤地坝内部泥沙颗粒级配的空间变化,明晰了淤地坝淤粗排细的机理。针对淤地坝的淤粗排细作用,对现行淤地坝工程设计提出改进设想,进而为淤地坝的可持续性利用以及工程设计提供更加完备的理论和技术依据。

Through conducts the silt siltation rule research to the different engineering structure silt dam, thus has promulgated the silt dam interior silt pellet gradation spatial variation, defined silt dam silt thick platoon thin mechanism. In view of silt dam silt thick platoon thin fimction, proposes the improvement tentative plan to the present silt dam engineering design, then provides a more complete theory and the technical basis for the silt dam sustainable use as well as the engineering design.
