大连南部滨海大道工程主桥为海上三跨地锚式悬索桥，两个锚碇的基础均采用超大沉箱结构，单个沉箱尺寸为72 m×47 m ×17 m （包括趾），重量约26000 t，为目前国内最大的沉箱。通过优化设计，物模试验，现场实际操作等方法，形成了超大沉箱设计、预制、出运、安装等一系列的关键技术成果。超大沉箱施工技术不仅是一个量的突破，更是一个思路的创新，对类似工程具有借鉴意义。

The main bridge on the coastal road in Southern Dalian is a ground-anchored three-span suspension bridge with two anchor foundations being built of large caissons. Each caisson is 72 mí47 mí17 m(including the toes),weighing about 26 000 t,and is currently the largest caisson built in China. By optimizing the designs,physical model testing,and actual operation on site,a set of key technologies for design,prefabrication,shipment,and installation of very large caissons were developed, which are not only a breakthrough in quantity but also an idea innovation, providing reference for similar projects.
