山东省黄河河务部门积极开展淤背固堤,利用黄河泥沙加宽加固黄河堤防,取得了显著的防洪效益和经济效益。经过今年黄河第一、二号洪峰检验,未经淤背加固的堤段多次出现渗水、管涌等险情,而经淤背加固的堤段却安然无恙。实践证明,淤背固堤是加固黄河堤防、确保防洪安全的一项有效措施。黄河是世界上输沙量最大的河流,每年有 Shandong Yellow River River departments actively carry out silt dikes embankment, the Yellow River sediment to broaden and strengthen the Yellow River embankment, and achieved significant flood control benefits and economic benefits. After this year’s Yellow River No. 1 and No. 2 flood peak inspection, the embankment sections reinforced without silt-back repeatedly appeared dangerous conditions such as seepage and piping, while the embankment sections reinforced by silt-back were intact. Practice has proved that silt ditch embankment is to strengthen the embankment of the Yellow River to ensure flood safety is an effective measure. The Yellow River is the world’s largest river for sediment discharge each year
