Abstract: The traditional piling model applied in projects of building coastal bridges requires the combination of two GPS systems, two tiltmeters or two rangefinders for positioning, which will fail if any device breaks down. This paper proposes a new fusion piling model that combines three GPS systems, two tiltmeters and two rangefinders. When one device breaks down, the problem will be monitored through an intelligent system, and a best choice will be made about the remaining devices to continue positioning. The new model can greatly improve the work efficiency.
