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.
