摘要
海洋工程的海底管线和桩等圆管结构,需先在岸上预制然后装船运送到施工地点再行安装。由于这种结构物的尺度和重量较大,运输期间在运输船产生横向和纵向的摇摆以及升沉运动时,会对船体和挡板产生很大的附加动荷载。分析了管状物在装船状态下的运动特性,计算了堆积的管状物在船横摇状态下对挡板的作用力,并通过模型试验进行了验证,试验结果与理论值吻合较好。该研究成果可供装船设计人员参考。
Some pipe ocean structures,such as piles,pipelines,have to be manufactured on land and transported to the installation sites by boat.Because the dimension and weight of the pipe structures are usually large,the pipe structures will induce considerable additional dynamic loads to the retainer because of the movement,such as rolling,pitching heaving,of the boat during transportation.The movement characteristics of the pipe structures are analyzed and formulas for calculating the dynamic load of the pipe structure on the retainer are also deduced.A model test device is designed and the test results agree well with the theoretical formulas.This approach can be used to help the designers to load pipe structures on a transport boat.
