摘要
传统护岸块体结构简单,功能单一,多年来对生态环境产生了不利的影响。为了改善这一状况,在鱼类对孔隙的选择性试验的基础上,对生态护岸块体进行了重新设计,设计出了多孔型生态护岸块体。新型式的护岸块体具有很多比较大的孔隙,供鱼类穿梭和栖息;植生孔的增加为水生植物提供了生长环境;为了保证块体的稳定性,为护岸块体设计了嵌插结构,这也使护岸的连接更加多样,以便适应更多地形。通过多孔型生态护岸块体的稳定性分析,确定了3种满足稳定需求的块体设计尺寸。
Blocks of traditional revetment have simple structure and single function, and traditional revetment has a negative effect on the environment for years. To improve this situation, based on the experimental research on the selectivity of fish towards the pore, the block of ecological revetment is redesigned. And the porous ecological revetment block is designed. The new block of revetment has many big pores, and fishes swim around it and live in it. Pore of plant growth provides space for growing aquatic plants. To guarantee the stability of the blocks, this paper designs the embedded structure and diversifies the connection of blocks to accommodate a variety of terrains. Through an analysis of the stability of porous ecological revetment block, three design sizes of block that meet the stability requirements are defined.
