The impact of grouting to the bottom of piles to the bearing capacity of large-diameter and extra piles setting into rock

摘要

In the area where hard formation buries deeply, large-diameter and extralong piles set into incompeternt rock with high pressure grouting may raise the bearing capacity and reduce settlement. As a result, it is not necessary to set too deep into hardformation unrealistically. This article approaches the subject through date of comparing two groups of piles experiments in the same project.
