| Abstract: | 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. |
