城市河道的景观型堤防设计

Research on Landscape-style Dike Design Method in Urban River

针对城市河道的堤防成为隔阻视线通达水岸空间的屏障,影响滨河景观建设和亲水空间营建建设的不利因素,提出在满足防洪功能基础上,综合考虑堤防自身和与周边环境融合的景观价值,以及利于植物生长、生物生息的生态价值,营建景观型堤防的理念。阐述了合理确定适宜的堤线位置,选择理想景观型堤防材料的方法;并在实践中总结或创新了复式断面营建亲水空间,多种形式组合处理堤坡,以及错层建筑分隔法等消除堤防高差视觉不利影响的方法。

Abstract： The dikes in the urban rivers have become a barrier for the waterfront space sight, which can affect the constructions of riparian landscape and hydrophilic space. Due to these disadvantages, a concept for the construction of landscape-style dikes is proposed to satisfy the flood control function, which combines the landscape values of the dikes and the surrounding environment, and the ecologic values which are favorable for plant growth and biological habitat. The methods to determine the reasonable and appropriate embankment line locations and to select the ideal landscape embankment materials are illustrated. Finally, several methods are summarized to build the landscape-style dikes including the compound section construction of the hydrophilic space, the multi-form slope process, and the separation of the split-level buildings, which can eliminate the adverse effects of dike height difference vision.
