摘要

[目的] 查明2013年7月延河流域连续出现的5次范围广

历时长

量级大的强降雨条件下淤地坝的运行及毁坏情况。[方法] 对延河流域3县区15个小流域45座淤地坝进行实地考察。[结果] 被调查淤地坝中35座经受住了暴雨洪水的袭击。遭毁坏的10座淤地坝中9座为已淤满变为耕地的"闷葫芦"坝(一大件)及1座新建坝。而尚未淤满正在发挥作用的淤地坝以及新旧结合的坝系大多数都正常运行。[结论] 延河流域该次淤地坝毁坏的直接原因是高强度和持续集中降雨造成的超标准暴雨洪水

同时淤地坝在建设、运行和管理方面也存在诸多问题。

Abstract

[Objective] To find out the running and damaged condition of check dams in the five heavy rainfalls with wide range

long duration and large magnitude in July 2013 in the Yanhe river basin. [Methods] Field survey of 45 check dams in 15 small basins of 3 counties in the Yanhe river basin was conducted. [Results] It was found that 35 check dams could withstand the storm and flood struck. While only one new dam and 9 old check dams transformed to cultivated land were destroyed. The dams

which was still not full of silt and the dam system of the new dam combined with the old dam

worked very well. [Conclusion] The direct cause of the destroy of check dams was the over-standard rainstorms and floods caused by intense and concentrated rainfall. Meanwhile

there are many problems in the construction

operation and management of check dams in the Yanhe river Basin.
