船舶撞击荷载作用下高桩码头结构损伤诊断及可靠度研究

Damage Diagnosis and Reliability for High-Pile Wharf under Ship Impact Load

根据国内外对船舶撞击荷载下高桩码头结构的研究现状,分析传统的经验公式法、试验方法以及有限元分析法在处理撞击荷载时存在的局限性,提出考虑动力放大效应的方法。结合时变可靠度理论,对高桩码头船舶撞击力进行动力分析,并对撞击荷载作用下高桩码头结构的研究方向进行展望。

According to the research status of the high-pile wharf structure under the impact load of ship at home and abroad, the limitations of the traditional experience formula method, the experimental method and the finite element analysis method to deal with the ship impact load are systematically analyzed. A method considering the effect of dynamic amplification is proposed. Considering time-variant reliability, the dynamic analysis of ship impact load for the high-pile wharf is presented. More than that, some research prospects of this problem are discussed.
