- On the basis of numerical simulations and by use of semi-empirical formulae, calculations of seabed erosion and siltation in and outside the fishing port are made. 在此基础上,利用半经验公式,进行了渔港内外底床冲淤计算。
- In this paper,erosion and siltation performance of low sheet-pile groins with different water permeability under tidal bore is studied by means of movable-bed model, and mechanism of flat-maintenance and dyke-protection is discussed. 本文在水槽中用动床模型试验手段研究了涌潮条件下不同透水率的排桩式护塘低丁坝群的水力学冲淤特性 ,并探讨了低丁坝的护滩保塘机理。
- Yanhe River is a river with hyper-concentration load.Stream channel erosion and siltation happens quite often during the flood season, which makes the shape of flood hydrograph protean. 由于延河汛期多发生高含沙水流,河道冲淤变形严重,洪水特性变化多端,成为预报的难点。
- In this paper, the mechanism of erosion caused by synergism of cavitation erosion and silt erosion was preliminary explained, and introduced a new method to study on the problem of erosion. 本文初步揭示了空蚀和泥沙磨损联合作用对材料产生破坏的作用机理,提出了一种研究材料在颗粒冲击磨损作用下破坏情况的新方法。
