某工程船坐底工况底座基梁载荷计算及船体结构强度校核

Calculation of the Loads on the Foundation Beam under the Bottom Supported Condition of Workboat and the Strength Assessment of Hull Girder

考虑工程项目需要混凝土预制件必须在工程船处于坐底状态时滚装上船的要求,将底座基梁所承受的载荷作为底座基梁的设计要素之一。同时,认为船舶处于坐底状态时船体梁的强度问题是工程成败的关键因素。通过有限元方法求解各底座基梁所承受的压力,并将其作为底座基梁的设计前提,同时完成船体梁的强度校核。

Because the concrete structures must be Ro/Ro to the ship under bottom supported condition of the workboat , the loading acting upon the bottom foundation beam is important to the design of the bottom foundation beam .The hull girder strength of the workboat in the bottom supported condition is also the key factor of the project .Through finite element analysis , the pres-sure on the bottom foundation beam was calculated to design the bottom foundation beam , and the hull girder strength of the work-boat was assessed at the same time .
