摘要
对于柔性靠船桩与码头之间是否需要设置护舷,前沿有护舷的柔性靠船桩计算方法等问题仍需要进行研究。采用Abaqus有限元软件对两侧均有护舷的钢管靠船桩进行分析,认为靠船桩宜采用p-y曲线法,内侧护舷按非线性弹簧进行分析计算,并结合工程实例对靠船桩进行优化设计。结果表明,内侧护舷的设置有助于降低靠船桩内力;钢管桩采用高强度钢材,采取局部加强能显著提高靠船桩性能。
It is still necessary to study whether fender should be installed between fender pile and wharf and the calculation method of fender pile with fender in front of berth pile.In this paper,Abaqus finite element analysis software is used to analyze the steel fender pile with fender on both sides.It is believed that the fender pile can be analyzed by p-y curve method,and the inner fender is analyzed by nonlinear spring.The optimal design of the fender pile is carried out by engineering examples combined with an engineering example.The results show that the inner fender is helpful to reduce the internal force of fender pile.The steel tube pile is made of high strength steel,and the local strengthening of steel tube pile can significantly improve the performance of fender pile.
