风浪联合作用下电厂码头驳船系泊试验研究
|
摘要
文章通过几何比尺1:50的物理模型试验,对14 000 DWT驳船在风、波浪荷载不同组合工况下船舶系泊运动量、缆绳拉力、护舷承受的撞击力,以及船舶靠泊产生的撞击力和撞击能量等进行了研究。分析表明,艏艉缆与码头前沿夹角变大时可分担部分横缆受力,从而使各个缆绳的受力更为均匀;在艏、艉与码头前沿夹角为59°～60°时,港内波浪周期在12 s时,限制波浪工况为H_(4%)≤0. 6 m,满足安全的靠泊速度需小于等于0. 2 m/s。
Physical model experiment with 1: 50 model scale was taken to test the mooring motion,cable tension,impact force on fender for 14 000 DWT barge with different combinations of wind and waves,as well as collision force and energy generated by berthing were studied. The analysis shows that when the angle between bow or stern cable and wharf front increases,part of transverse cable force can be shared,so that the force on each cable is more uniform. At the angle of 59° ～ 60°,when the wave period is 12 s and wave height is limited to H_(4%)≤0. 6 m,the safe berthing speed should be less than or equal to 0. 2 m/s.
