Field Tests on Behavior of Pre-bored Grouted Planted Pile in Soft Soil Area with Existing Pile Foundation
Abstract This paper presents a practical renewal project in soft soil area, and the site foundation should be improved owing to the increasing load from superstructure. The installation of “new” pile foundation was a great challenge due to the existing square piles in the foundation. A group of field tests were conducted to investigate the compressive bearing capacity of the PGP pile and bored pile, and the applicability of these two piles in soft soil area with existing pile foundation was also studied. The results show that the ultimate unit skin friction of the PGP pile is about 1.22 times the ultimate unit skin friction of the bored pile. The PGP pile was chosen as the foundation of this renewal project, and the existing square piles around were scarcely disturbed during the PGP pile installation process.
