传统的沉箱海上定位安装施工工艺是采用方驳或浮吊进行定位，但对于2.6万吨级的超大型沉箱，该定位方法显然无法实现。文章对2.6万吨级的超大型沉箱进行海上缆系定位与锚系定位两种方法的试验研究，得到了大型沉箱海上定位时适宜的波、流条件以及相关注意事项，为大型沉箱定位安装及类似工程提供参考和借鉴。

The traditional method of the offshore caisson positioning and installing is using the barge or floating crane, but for the large caisson with 26 000 tons, the method is unable to achieve apparently. This paper studies the offshore location and installation of the large caisson with mooring line system and anchor cable system, gets the feasible wave and flow conditions during the offshore positioning of large caisson, as well as the related and advertent items, which provide the reference for large caisson positioning and installation as well as the similar engineering construction technology.
