【摘要】 结合长江河口地区某码头处的水文地质条件 ,工程 (包括断桩 )实测资料 ,对涨潮急流作用条件下码头基桩的工作性状加以分析研究。码头断桩的原因是基桩泥表面被严重刷深 ,涨潮时流速过大及基桩的剧烈晃动所致。提出涨潮急流下码头基桩内力的分析计算方法及基桩的振动分析方法更多还原

【Abstract】 Based on the hydrographical and geological conditions and real-measured engineering data(including broken piles)of a wharf at the Yangtze Estuary section, it gives an analysis and research to the functional mode of wharf foundation pile under flood tide torrent.The causes for broken piles of wharf lie in the serious scouring of silt surface(in depth)around foundation pile, too high speed of flood tide current and violent swaying of foundation pile. The method of analyzing and calculating the internal force of wharf foundation pile and vibration analysis method for foundation pile under flood tide torrent are advanced.更多还原
