Effectiveness of post-grouting on the vertical response improvement for extra-long bored piles: case studies on field tests [PDF]
The current engineering practice has shown that post-grouting improves the vertical bearing capacity of bored piles. However, some engineers are concerned about the effectiveness of post-grouting in the context of extra-long bored piles.

Prediction of long pile tip resistance based on CTNOA-SBL-MIC model [PDF]
Machine learning (ML) has been widely used in pile foundation engineering modeling. However, predicting pile tip resistance of long piles remains a significant challenge, as pile tip resistance becomes substantial only when the pile is loaded and ...

Experimental and theoretical research on large-diameter rock-socketed pile embedded depth [PDF]
A theoretical formula for large-diameter rock-socket depth is developed to support pail embedding in a large bridge pile foundation project. There is a horizontal additional stress concentration at the place where the soil around the rock-socketed pile ...
