海底沉管法隧道测量塔结构设计计算分析

Structural Calculation and Analysis of Measurement Tower of Subsea Immersed Tunnel

测量塔是管节沉放过程中测量管节平面位置、姿态、高程的重要结构。结合实际工程,根据现有国家规范标准,梳理海底沉管法隧道测量塔在复杂海洋环境条件中风、波浪、水流等荷载作用下相关设计计算要点。所得结论可供同类工程参考借鉴。

A measurement tower is an important structure for measuring the plane position,attitude and elevation of immersed elements during the immersion process.Combined with the actual project,according to the existing national specifications and standards,the key points in structural design and calculation of the measurement tower under the wind,wave,current and other loads of complex marine environmental condition are summarized,which can be referred for the similar projects.
