摘要
钢管桩是高桩码头的主要结构型式之一,尤其是在深海中应用十分广泛。目前码头工程中一般采用剪力键连接钢管桩与码头上部结构,其连接机制与剪力键的尺寸、间距密切相关。发展至今,取得了丰富的研究成果,但仍存在一些技术难题。本文基于国内外大量文献资料,从理论研究、模型实验、物理模型三个方面对二者的连接机制进行系统地阐述,并提出了下一阶段所需要重点研究的问题,为后续剪力键的研究打下基础。
As one of piled berth structures,steel pipe pile structure has been widely used in deep sea projects.At present,shear keys are generally adopted to connect steel pipe piles with the upper berth structure.The connecting mechanism is closely related to the size and spacing of shear keys.Up to now,some rich research results have been achieved,but some technical problems need to be solved.Based on a great amount of documentation from home and abroad,the connecting mechanism is systematically expatiated from such aspects as theoretical study,model test and physical model,and the key subjects at the next stage are put forward,which lays a foundation for the subsequent research of shear key.
