“…The improvement effect of base grouting on the side friction has been proved by extensive field monitoring data, which show that the post-grouted piles achieve higher side friction than the non-grouted ones [2][3][4][5][6][7][8]. In routine practice, the penetration height of the grout from the pile base is regarded as the reinforcement height of the side friction [9].…”

Post-pressure grouting is an effective method to improve bearing capacity of ordinary bored cast-in-situ piles. The migration of the grout along the pile side is regarded as an important mechanism responsible for the improvement of the pile capacity. Research into the penetration height of the grout is of great important in evaluating the behavior of base grouted piles. In this paper, a prediction method of grouting penetration height along the shaft of the base grouted pile was proposed. Considering the balance and losses of the grout pressure during grouting, an iterative procedure was given to determine the penetration height of the grout in layered soils. Field test results were also provided to indicate the validity of the proposed method.

Pile foundations for offshore structures can be installed in different ways, with this article focusing on two main pile types: (i) driven; and (ii) drilled and grouted. An overview of simplified mechanics‐based concepts for issues affecting analysis of pile installation is provided. For driven piles, the concepts considered include soil resistance to driving, dynamic soil models, and pile damage. For drilled and grouted piles, attention is focused on methods to avoid hole collapse and hydraulic fracture. With these concepts in mind, a designer can minimize the potential for costly remedial activities that may be required during pile installation if the above issues have not been adequately addressed.
