| Abstract: | For the immersed tube tunnel construction process, due to structure security and the need of construction orientation, sink must be precise measurements at the scene to put seawater density values at each stage. Based on a large bay immersed tube tunnel engineering heavy put operation in the process of practical operation, it put forward the fast and accurate seawater density field measurement method, which can be used for reference in the similar engineering projects. |
