摘要
根据山区河湾路基边坡冲刷特点,建立路基边坡上填料单颗粒三维受力模式,对凹岸路基路边坡填料颗粒冲刷起动的基本条件进行理论推导。通过算例结果分析,探讨不同水流近底流速条件下的凹岸路基边坡抗冲稳定坡度。
In accordance with the features of erosion for slope on embayment roadbed in mountainous area, this paper establishes the single-grain three-dimensional loading modes of fillers on slope of roadbed to derive the basic conditions for starting grain erosion of fillers on slope of roadbed on cutbank in theory. The paper via the analysis for results of calculation examples probes into the stable resistance to impact and o erosion of slope on roadbed on cutbank under different velocities of water flow near the bottom.
