摘要
深中通道是国内继港珠澳大桥后又一条世界级“桥、岛、隧、地下互通”的集群工程。该工程建设条件复杂,沉管管节结构超宽、超长、埋深超深,给工程设计和施工带来极大的挑战。设计中创造性提出采用钢壳混凝土组合结构方案,以解决结构受力难题,降低工程风险。这也是目前世界上首例采用钢壳混凝土组合结构建设的双向8车道沉管法隧道。就深中通道沉管法隧道在设计和施工中的关键技术进行介绍和分析,以供今后类似工程借鉴。
Shenzhen-Zhongshan Passage is another world-class project composed of"bridge,island,tunnel and underground interchange"after the Hong Kong-Zhuhai-Macao Bridge Project in China.The complex construction condition,extra wide and long immersed element and extra deep embedment bring great challenges to the engineering design and construction.In order to deal with the structural stress and reduce the engineering risk,the steel-concrete sandwich structure is proposed for the immersed element creatively.This is the world’s first bi-directional 8-lane immersed tunnel built with steel-concrete sandwich structure.The key technologies in the design and construction of the immersed tunnel are introduced and analyzed,which can be referred for the similar projects in the future.
