Dynamic testing of cast-in-place piles

This is a preliminary investigation which, it is hoped, may lead to the development of a simple technique for determining the soundness and quality of a cast-in-place piles to detect anomalies has been carried out (4), but the method attempted requires coring and the installation of special equipment in the pile, thus rendering the method expensive. The technique described in this note requires no special installation in the pile. If proven satisfactory it can be used to identify those piles that need to be either discarded or load-tested to ascertain their static load-carrying capacity.Peer reviewed: NoNRC publication: Ye
