The invention relates to an immersed tube joint floating-state barge construction control method, which can realize safe and rapid barge of immersed tube joints by establishing a multi-parameter system comprising monitoring parameters, control parameters and regulation and control parameters. The maximum oil pressure difference value of three areas of transportation equipment is adjusted and controlled through the oil pressure of the transportation equipment, and it is guaranteed that immersed tube joints do not crack in the barge-up process; the height of a buttress on a ship is adjusted based on numerical calculation before loading, the deflection of a semi-submersible barge is controlled based on load adjustment of the semi-submersible barge in the pier falling process, and it is guaranteed that immersed tube joints do not crack in the pier falling process; a load adjusting scheme is formulated according to the loading speed and the tide level change before loading implementation, the height difference between a wharf surface and a stern deck surface and the floating state of the semi-submersible barge are controlled to meet corresponding control indexes based on loading speed adjustment and semi-submersible barge load adjustment in the loading process, and smooth walking of transportation equipment and stability and safety of the semi-submersible barge in the loading process are guaranteed; and the immersed tube joint can be safely connected.
本发明涉及一种沉管管节浮态上驳施工控制方法,能够通过建立包括监测参数、控制参数、调控参数的多参数体系,实现沉管管节安全快速上驳;通过运输设备油压调节控制运输设备三区油压最大差值,保证上驳过程中沉管管节不开裂;通过在上驳实施前基于数值计算调节船上支墩高度,落墩过程中基于半潜驳调载控制半潜驳挠度,保证落墩过程中沉管管节不开裂;通过上驳实施前根据上驳速度、潮位变化制定调载方案,上驳过程中基于上驳速度调节、半潜驳调载控制码头面与船艉甲板面高差、半潜驳浮态满足对应的控制指标,保证上驳过程中运输设备顺利行走和半潜驳稳性安全,实现沉管管节安全上驳。
