浅谈黄河山东区段挖河固堤

Ditching River to Solide Dam in the Reaches of the Yellow River in Shandong Province

黄河下游山东窄河段由于泥沙淤积河床逐年抬高，挖河疏浚作为解决主河槽减淤的主要途径之一进行实践和研究。挖出的泥沙可以加固堤防或淤填串沟。挖河固堤首先要做好启动工程，挖河施工可根据水文和地形条件选旱挖、船挖、组合泵挖等不同施工方法，并加强挖河固堤观测试验研究。

Due to silt increasely, the river bed has been made higher year by year at the lowerreaches of the Yellow River in Shandong province. Ditching river to solide dam as an importantway to prevent the river bed from silting is becoming practised and researched. In order to doing this well, the first thing is to operate the engineering. According to the hydrologic and geographic conditions, the different work methods such as dry digging, boat ditching etc. can beselected. At the same time, the survey for ditching river to solide dam should be strengthen.
