【摘要】 城市人工湖对改善城市生态环境具有重要作用,但修建或维护不当易产生水体富营养化等生态问题。本文从人工湖的生态防渗衬砌着手,分刚性防渗和柔性防渗讨论了常规防渗衬砌的生态影响,提出生态防渗衬砌设计应考虑的几个原则,并在此基础上探讨了土料防渗、膨润土防渗毯、土壤固化剂及新型膜料防渗等生态防渗的结构方案,为人工湖的生态建设提供参考。更多还原

【Abstract】 Man-made lake plays an important role in improving the city’s ecological environment,however,its improper building or maintenance easily leads to ecological problems such as water eutrophication.In this paper,we focus on the eco-impermeable lining in man-made lakes.The conventional seepage structure is classified in two types:rigid structure and soft structure,and based on their ecological effects,several principles of eco-impermeable lining design are proposed.In addition,new ecological seepage structures such as impervious soil material,bentonite seepage blanket,soil stabilizer and new membrane material are investigated to provide reference for man-made lake building.更多还原
