【摘要】 作者在特制的高速水流试验陡槽的天然基岩河床上,进行了大比尺挑流冲刷的模型试验.结合分析试验成果,参考了国内外原型观测和模型试验的资料,探讨了基岩挑流冲刷破坏的机理,着重讨论了基岩构造完整程度、岩层产状的不同、胶结程度优劣等影响因素.更多还原

【Abstract】 With high-velocity in specially made test chute, the authors performed a large-scale model test with jet scouring on a natucal bedrock. Analysing the test result and consulting the imformation from prototype observation and model tests, the mechanism of jet scouring is investigated. In this paper, emphasis is placed on discussion of the effect of some factors, such as the integrity degree of bedrock. the state of stratum, and the degree of cementation.更多还原
