Abstract

Abstract

This article analyses the pile foundation which is not qualified for the integrity and bearing capacity by the drill grouting piles test in the marine mucky soil area.The main reason has been found out that the drill grouting piles in marine mucky soil area will lead to concrete excursion and erosion.Meantime,this article also studied how to utilize the current pile foundation bearing capacity via acceptance test,additional test and design load audit,further strengthen the pile foundation and save invest cost.
- auger drilling grouting pile,
- individual pile bearing capacity,
- pile integrity,
- foundation reinforcement,
- marine mucky soil
