| 摘 要： | 根据近10 a观音庙险段的实测资料,分析了横断面、深泓断面、冲淤变化、水流特性等变化特点,结果显示,2005—2016年间,该险段河床下切近9 m,险情加剧。分析成因主要由洪水侵袭、来沙量与水流挟沙能力不适、水流特性复杂引起。建议非工程措施与工程措施相结合,科学治理险段。

| Abstract: | According to the measured data in recent 10 years of Guanyinmiao dangerous reach of Beijiang River, cross section, thalweg section, change of scour and silting and flow characteristics are analyzed. Results show that river bed is 9m deepened intensifying the dangers from the year of 2005 to 2016. And the causes have been analyzed, it turns out the main reasons are flood, the amount of incoming sediment not match sediment-carrying capacity and flow characteristics. Thus, it is recommended that non-engineering measures is scientifically worked with engineering measures while treating dangerous reach. |
