强震作用下全直桩码头桩基泥面以下弯矩控制的抗震设计

摘要

由于全直桩码头桩基泥面以下塑性损伤往往难以修复，着重尝试探讨强震区基于桩基泥面以下弯矩控制的全直桩码头结构的抗震设计，以确保强震作用下泥面以下桩基保持弹性。提出了基于桩基泥面以下弯矩控制的结构抗震设计方法，并重点阐述了其理论依据、主要假定及逐步分析步骤。研究表明桩基泥面以下弯矩是控制全直桩码头抗震设计的重要有效参数之一。%The plastic damage on the pile under the mudline are often difficult to repair, this paper focuses on the seismic design of pile moment control under the mudline for the vertically piled wharf in the highly strong-earthquake-prone region, in order to ensure that the pile under the mudline remains elastic. The seismic design method of pile moment control under the mudline controlled is proposed, with emphasis on its theoretical foundation, underlying assumptions, and the step-by-step design proce-dure. The results show that the pile moment under the mudline is one of the important effective parameters to controlling the seis-mic design of the vertically piled wharf.
