中文摘要：
依托汉江崔家营航电枢纽工程施工期导流明渠运行期的原型观测,对比导流明渠运行期河床的冲淤变化,并结合不同流量下的流速、流态,分析导流明渠防护工程的防护效果以及范围的合理性。分析表明：守护工程整体是稳定的,防护效果较好,特别是岸坡防护工程基本未发生破坏现象;导流明渠下段护脚工程发生了冲刷破坏,为了岸坡的整体稳定,应适当扩大守护宽度;导流明渠下游段的守护范围可适当下延。
英文摘要：
Based on the prototype model test of the open diversion channel used for flow discharge and navigation during the construction of Cuijiaying junction, we study the erosion-deposition variation in the channel and analyze the effect of the protection works and the rationality of the protected range according to the flow regime and velocity in different discharges. These research results show that the protected works are stable in general, and these protection works are very effective, especially the works for bank slope, almost none of them are destroyed; Some toe protection works in the downstream of the channel are destroyed badly, so the protected range of theses works ＂should be widened for the stability of the bank slope; Moreover, the protected range in the downstream of the channel can be properly extended.
