新型防洪墙在山区河流上的应用

Application of a new type of flood control wall in mountainous rivers

因沿江梯级建设带来的水位壅高影响或原城市已建堤防的标准本身偏低,现状堤防标准往往不能满足规范要求,需要加高处理。以岷江黄旗坝防护堤设计为例,提出几种新型防洪墙结构形式,对比分析其优劣。根据不同防洪墙结构特点,论证新型防洪墙在山区河流、城市堤防中的适用性。

Due to the high water level caused by the cascade construction along the river or the low standard of the built embankment in the original city,the current levee standards often fail to meet the requirements of the specifications and need to be heightened.Taking the design of Huangqiba protection dike in Minjiang River as an example,this paper puts forward several new types of flood control wall structure,and compares and analyzes their advantages and disadvantages.According to the structural characteristics of different flood control walls,the applicability of the new type of flood control wall in mountainous rivers and urban embankments is demonstrated.
