黄河干流上游段防洪工程护岸及护坡技术方案探究

Study on technical scheme of bank protection and slope protection of flood control project in upper reaches of Yellow River Main Stream

黄河干流上游河段河岸多为临河陡坎形式,岸坡岩性为冲洪积层,稳定性较差。每次较大洪水都会造成沿岸草场、林地坍塌,并危及公路的安全,造成巨大经济损失。针对以上问题,文中对护岸及护坡结构形式、护坡材料等选择4种技术方案进行比选,并对选定的护岸方案进行典型设计分析及高边坡设计分析,设计成果可为类似河道整治提供技术依据及经验参考。

The banks of the upper reaches of the main stream of the Yellow River are mostly in the form of steep slope, and the lithology of the bank slope is alluvial-diluvial layer, which has poor stability. Each major flood will cause the collapse of coastal grasslands,woodland, and endanger the safety of roads, causing huge economic losses. In view of the above problems, this paper compares and selects four technical schemes of bank protection and slope protection structure form and slope protection materials, and analyzes the typical design and high slope design of the selected bank protection schemes. The design results can provide technical basis and empirical reference for similar river regulation.
