河道整治分類
Classification of river regulation
為防 洪、航運、供水、排水及河岸洲灘的合理利用,按河道演變的規律,因勢利導,調整、穩定河道主流位置,以改善水流、泥沙運動和河床沖淤部位的工程措施。河道整治分兩大類:①山區河道整治。主要有渠化航道、炸礁、除障、改善流態與局部疏浚等。②平原河道整治(含河口段)。主要有控制和調整河勢、裁彎取直、河道展寬及疏浚等。中國有4000年前禹疏九河,導流入海的傳說。明代的潘季馴治理黃河頗有成效,他還著有《河防一覽》,其中“以河治河,束水攻沙”的理論,具有創見性和科學性,流傳久遠。隨著近代水力學、河流動力學、河道泥沙工程學的進步,河工模型試驗的發展及工程材料的改進,河道整治發展到一個新的階段。
In order to prevent flood, navigation, water supply, drainage and rational utilization of river bank and shoal, according to the law of river course evolution, adjust and stabilize the position of river channel according to the situation, so as to improve the flow, sediment movement and the engineering measures of river bed scouring and silting. River regulation is divided into two main categories: 1. River regulation in mountainous areas. There are mainly channelized channel, reef blasting, removal of barriers, improvement of flow pattern and partial dredging. 2. Plain river regulation (including estuaries). It mainly controls and adjusts river regime, straightening and straightening, widening river channels and dredging. China has 4000 years ago the legend of Yu nine rivers and the diversion into the sea. In the Ming Dynasty, Pan Jixun had achieved great success in harnessing the Yellow River. He also wrote A Survey of River Prevention, in which the theory of "harnessing rivers by means of rivers and attacking sediment by means of water" was original and scientific and had a long history. With the progress of modern hydraulics, river dynamics and river sediment engineering, the development of river model test and the improvement of Engineering materials, river regulation has developed to a new stage.
