摘　　要：针对港口工程高桩码头基桩施工过程中出现超高、打低、偏位、桩头开裂、桩身裂缝,以及灌注桩、嵌岩桩在施工过程中出现的完整性异常、承载力不足等问题进行分析,提出割桩、局部减低上部结构高程、局部加大上部结构截面、增加桩帽、接桩、补桩、包裹补强、后注浆等处理技术。通过工程实例分析后注浆加固补强措施对承载力提高的效果,为灌注桩、嵌岩桩常见问题处理技术提供数据支撑。研究成果可为高桩码头结构基桩处理提供参考。To solve the problems of over-height,under-height,deviation,cracking of pile head,and pile body cracks,as well as the integrity anomalies and insufficient bearing capacity of cast-in-place piles and embedded piles during the construction of foundation piles of high-pile wharves in port engineering,this paper proposes cutting piles,partially lowering the elevation of the upper structure,partially increasing the cross-sectional area of the upper structure,adding pile caps,splicing piles,filling piles,reinforcing with wrapping,and post-grouting treatment technologies.Through the analysis of the effect of post-grouting reinforcement measures on bearing capacity improvement in engineering examples,it provides data support for the common problem treatment technologies of cast-in-place piles and embedded piles.The research results can provide reference for the treatment of foundation piles for high-pile wharves.
