摘要
采用胶凝砂砾石等刚性防洪堤对超标洪水具有较高的安全性,而且堤身断面小,可以节约土地资源,但是传统胶凝砂砾防洪堤忽略了堤防的生态功能。通过将犍为航电枢纽工程塘坝胶凝砂砾石防护堤与市政绿化设计相结合,探讨并提出兼顾防护堤卓越功能性与良好生态性能的实施方案。同时,对胶凝砂砾石防洪堤进行水土保持生态效益及社会效益分析。结果表明,胶凝砂砾石防洪堤可在满足防洪安全稳定的基础上兼顾市政绿化,达到绿色生态、景观优美的效果,可减少库岸土壤对水库的侵蚀量、保护生物多样性,比传统均质堤型更适合城市堤防。
The rigid flood bank such as the cemented gravel embankment is safer when facing excessive flood,and has smaller sections,with less land occupied,but the traditional cemented gravel embankment ignores the ecological function.By combining the ecological function with the cemented gravel embankment in the design of Tangba flood bank of Minjiang Qianwei navigation and power hub project,we propose the scheme considering both remarkable function and ecologic performance,and analyze the economic and social benefits of cemented gravel embankment's soil and water conservation.The result shows that the cemented gravel embankment can combine the safety property with ecological functions in many ways,and achieve the effect of green ecology and beautiful landscape,reduce the amount of soil erosion on the reservoir bank to protect biodiversity,thus it is more suitable for the urban embankment.
