The Influence of Construction “Side Effects” On Existing Pile Foundations.
This projects aims to explore some of the “side effects” of investigation and construction processes, and their possible effects on existing deep foundations. The processes considered include:
1. The driving of piles;
2. The installation of piles by jacking;
3. Drilling holes in stressed ground for the purposes of investigation or construction;
4. Carrying out shallow excavations, for example, for pile cap construction or the installation of services;
5. Carrying out deeper excavations, for example, for a development on a site adjacent to the existing pile foundation.
Each of these processes involves the generation of additional ground movements, which will in turn induce additional movements, forces and bending moments in the existing foundations. The project will examine these ground movements and explore their influence on the behaviour and integrity of existing pile foundations.
