摘要

探讨了坡面冲刷过程中土壤的受力情况、坡面流能量及其平衡。从土壤的冲刷起动拖曳力入手

得出了发生坡面冲刷的条件。最后给出了一个工程算例。

Abstract

The mechanical essence of slope surface scouring is the stability of s oils and the process of hydrodynamic action of slope surface flow on soils. From the viewpoint

the forces acting on soils

flow energy and its balance during t he process of slope surface scouring are studied . Through incipient motion drag force

it obtains the occurring conditions of scouring. And it provides an engi neering illustration.
