复合土工膜在海域工程干施工围堰中的应用

海域工程干施工围堰的截渗设计是干施工围堰设计的重点和难点。目前,大型海上施工围堰的截渗结构均为陆上施工,其工程造价高、工期长。某海域工程大型围堰首次应用复合土工膜获得成功,由于其可随围堰结构一起进行水上施工,因此,达到了缩短工期、降低工程造价的设计要求,可供今后此类工程设计参考。

Application of Composite Geomembranes in Dry Construction Cofferdam Project in Sea Area

The seepage prevention is the important and difficulty point in the design of dry construction cofferdam in sea area. At present, the large seepage prevention structure of cofferdam is usually constructed at land and the cost is high and construction period is long. The first successful application of composite geomembranes in large cofferdam shortens the construction period and reduces the project cost because it can be constructed under water together with the cofferdam structure. Which can be referred by the similar project.
