Abstract:From 1967 to 1970 an automated pier was built for the Comision Ejecutiva Portuaria Automata, at Acajutla, El Salvador. The pier was founded on piles sunk into volcanic tuff which is the rock native to the area. The final load testing program resulted in unacceptable settlement of certain piles, in excess of 0.4 in. (9 mm) and up to 2.1 in. (54 mm). A drilling and coring program revealed the following defects: 1. Segregation of coarse aggregate, sand, and cement in the concrete in the pile, or 2. Unstable ground at the base of the pile, or 3. Some combination of Defects I and 2. Water pressure testing following the drilling and coring program indicated that some grout collars between the piles and the volcanic tuff had been broken by the settlement.
