Method for determining and correcting tube joint weight and buoyancy center position of variable cross-section immersed tube
The invention discloses a method for determining and correcting the weight and buoyancy center position of a variable cross-section immersed tube joint, which aims at a special variable cross-section immersed tube joint structure, can standardly calculate the weight and buoyancy center position of the variable cross-section immersed tube joint, and further reasonably determines the fixed inclination height of the tube joint and controls the stability of the tube joint under various working conditions by determining the weight and buoyancy center position. And the safety and the stability of floating transportation in water saving of the variable-cross-section immersed tube are ensured. According to the method, the stress and deviation correction problems of the variable cross-section immersed tube joint in the floating and floating transportation processes are solved, the design difficulty is effectively reduced, and the construction control risk is reduced.
本发明公开了一种变截面沉管管节重、浮心位置的确定及纠偏方法，针对特殊的变截面沉管管节结构，可以规范计算变截面沉管管节重浮心位置，通过确定重浮心位置进而合理地确定管节定倾高度，控制管节在各种工况下的稳定性，保证变截面沉管管节水中浮运的安全性和稳定性。本发明克服了变截面沉管管节在起浮、浮运中的受力及纠偏问题，有效降低了设计难度，降低了施工控制风险。
