通过物理模型试验,对永定河三家店—卢沟桥河段水流流势及河床冲淤变化规律进行研究分析。给出各段纵、横断面冲淤变化规律;确定了该河段险工段;并提出河道整治方案,分析其整治效果。
Through the physical model test, the flow pattern of the Sanjiadian-Lugouqiao reach of the Yongding River and the variation of the riverbed scouring and silting were studied and analyzed. The variation rules of erosion and deposition in each section are given. The dangerous section of the section is determined. The scheme of river regulation is proposed and the effect of remediation is analyzed.
