摘　　要：传统的人工湖泊防渗措施主要采用混凝土防渗墙、铺砌、土工膜和膨润土毯、黏土等防渗方案,直接隔断了水体与土体的水分、氧气和物质的交换,生物和微生物难以生存,造成生态破坏。结合某人工湖的防渗设计实例,提出了以微生物灌浆为主的新型生态防渗体系,进行了三维渗流分析和生态环境评价,研究结果表明渗漏量相比于防渗前减少了98%,同时满足该人工湖泊各区域的生态需水量,可达到防渗与生态之间的平衡,可以为类似工程的防渗设计提供参考。Traditional seepage control measures for artificial lakes mainly rely on concrete cutoff wall,paving,geomembrane,bentonite waterproof blanket,clay and other seepage control schemes,which directly block the exchange of water,oxygen and substance between water body and soil,and it is difficult for organisms and microbes to survive,resulting in ecological destruction.Combined with an example of seepage control design for an artificial lake,a new ecological seepage control system based on microbial grouting is proposed.Three-dimensional seepage analysis and ecological environment evaluation are carried out.The research results show that the leakage amount is 98%less than that before seepage control,and the ecological water requirement of the artificial lake can be satisfied at the same time,and the balance between seepage control and ecology can be achieved,which can provide valuable reference for seepage control design of similar projects.
