摘　　要：针对湖泊水生态环境特点以及隧道工程围堰明挖法施工的特点,以某湖底隧道工程为例,对工程施工期环境保护方案进行研究,重点针对隧道施工中的围堰工程、基坑工程、淤泥处理处置、生态保护等方面的环境保护措施进行探讨,提出围堰抽排水及拆除时采取降低悬浮物浓度、基坑开挖的漆渣妥善处置、采用淤泥原位固化、防范蓝藻水华爆发等,以达到保护湖泊水生态环境的目标。According to the characteristics of lake water ecological environment and the characteristics of tunnel cofferdam open cut method construction,taking a Lake Tunnel project as an example,the environmental protection scheme during the construction period is studied,and the environmental protection measures in the aspects of Cofferdam Engineering,foundation pit engineering,sludge treatment and disposal,ecological protection and other aspects in tunnel construction are discussed,and the measures for cofferdam drainage and demolition are proposed In order to protect the ecological environment of lake water,low concentration of suspended solids,proper disposal of paint residue from excavation of foundation pit,in-situ solidification of sludge,prevention of cyanobacteria outbreak,etc.
