干法施工重力式沉箱码头要点分析

重力式沉箱码头干法施工在实际工程中十分少见。与湿法工艺相比,干法施工具有施工过程透明、施工精度高、施工进度快等优点。但是干法施工工程经验较少,而且与湿法施工工艺在某些地方存在较大的不同。以某干法施工的重力式沉箱码头为例,阐述干、湿法工艺的不同之处,并提出了在设计和施工中应采取的措施。

Key points of dry construction of gravity caisson quay-walls

Dry construction was rarely used in construction of gravity caisson quay-walls。Compared with the method of wet construction,dry construction has an edge over the latter in terms of its transparency in construction,precise engineering and shorter construction period.But there is little experience of dry construction,and construction technology of the dry construction is quite different from that of the wet construction in some aspects.Taking the application of dry construction of one gravity caisson quay-wall as an example,this paper illustrates the difference and puts forward suggestions on the design and construction measures.
