固定式海洋平台钢桩打桩分析

通过GRLWEAP打桩软件对钢桩打桩过程进行分析,计算连续打桩、短期停锤、长期停锤3个工况锤击数,分析钢桩打桩过程拒锤情况,并应用理论计算的方法组合钢桩打桩动应力以及自由站立静应力进行钢桩强度校核。综合2种计算结果,选择打桩锤型号,依据所选打桩锤计算钢桩自由站立,以满足打桩要求。

Discussion of Construction Related to Sheet-piled Wharf

In this paper, firstly, the characteristics of sheet-piled wharf construction are introduced. And then, six aspects of sheet-piled wharf construction are discussed： sheet pile, anchorage structure, guiding girder, anchor rod, backfilling behind sheet pile wall, superstructure of sheet-piled wharf etc. The construction of sheet pile involves piling on the land or piling？on？the sea, piling methods, piling patterns, guide frame, embedding sheet piles etc.
