沉管隧道结构设计与普通隧道的结构设计不同。沉管隧道管段不仅要满足结构受力要求，也要满足起浮及浮运期间的干舷高度，以及沉放和运营期间的抗浮安全系数要求。

The structure design of the immersed tunnel is dif-ferent from that of common tunnels. Immersed tunnel should not only meet the requirements of the structural force, but also to meet the freeboard height during floating and sinking, and the requirements of the coefficient of safety of anti-floating during the operation of the floating.
