Paper Title:
Load-Transfer Properties of Extra-Long Piles Embedded into Deep Hard-Rock and High-Pressure Grouting Piles Set into Fragmental Rock
  Abstract

In the area where hard formation buries deeply, large-diameter and extra-long cast-in-place piles set into soft fragmental rock with high pressure grouting technique may raise the bearing capacity and reduce settlement apparently. This article approaches and analyses the subject through testing data of comparing two groups of piles experiments with two different ways of construction in the same project. The research enhanced original designing arrangement, shortened construction period, reduced cost of the project and drew some valuable conclusions. As a result, it also proposed that it’s not necessary to elevate the length of piles worthlessly and set too deep into hard formation unrealistically to avoid wasting in the later similar engineering.
