摘要
人们普遍认为采用半潜驳出运、安装超过2 000 t的大型沉箱,采用浮吊船出运、安装低于500 t小沉箱较为适宜,而对500~2 000 t之间的中型沉箱采用何种方案出运、安装并未有统一意见。通过广西北海LNG接收站陆域形成工程,从环境、经济、技术方面进行分析比较,提出采用大型浮吊船（起重船）配合平板方驳出运、安装中型沉箱的优越性,并探讨施工措施。
It is widely appreciated that the launching,transportation and installation of 2 000 t plus largesized caisson can be conducted by the semi-submersible barge,and those of the small-sized caisson of less than 500 t can be conducted by the floating crane.However,there is not a common opinion on the launching,transportation and installation of medium-sized caisson between 500 t and 2 000 t.Taking the land formation engineering of Beihai LNG receiving station in Guangxi region as a study case,we expound the superiority of launching,transportation and installation of the medium caisson using large float crane combined with panel square barge from the aspects of the environment,economy and technology and probe into the relevant construction measures that must be paid attention to.
