Container Wharf with an Innovative Precast Deck in a High Seismicity Area
Bibliographic record
Abstract
Located on the remote Aguadulce Peninsula in Buenaventura on the Pacific coast of Colombia, the Sociedad Puerto Industrial de Aguadulce (SPIA) container wharf is a T-headed pile-supported wharf comprising a 600-meter-long quay connected to a 160-meter-long access trestle and a 25-meter-long platform. The wharf is designed to support Super Post-Panamax ship-to-shore cranes and berth 12,500-TEU container vessels. The marine contractor chose to build the wharf with a top-down construction system to expedite construction. The benefits of this system were maximized by the implementation of a deck system composed primarily of precast concrete (PC) elements over high-capacity driven steel pipe piles. The deck system involved the use of an innovative PC plug providing the connection between the pipe piles and the PC deck elements. The PC plugs had to not only provide structural performance equivalent to the widely accepted cast-in-place concrete plugs, but also had to be optimized for transportation and erection. This paper describes how the different PC elements forming the wharf deck system were designed, detailed, erected, and connected. The paper also presents key results of the seismic analyses and design. The design of the deck was particularly challenging because of the need to implement seismic capacity protection principles in one of the world’s highest seismic areas. The paper also elaborates on how the top-down construction system was implemented. This system lends itself to a linear construction approach that uses previously-installed steel pipe piles as supporting elements of a platform that rapidly installs future piles and PC deck elements and then moves forward to continue with the rest of construction.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
