Chenglong Liu · Highway · 2005
Through the construction practice of the trestle over the north principal channel of Hangzhou Gulf Bridge, under the condition of a pile driving barge without equipments of the commercial GPS positioning system for offshore pile driving, a new method of marine driving positioned by the use of normal surveying instruments is presented, and the rapid and accurate survey for positioning steel-pipe piles achieved. By the check to the deviation of driven piles, it indicates that the method can completely meet the precision of surveying positioning to steel-pipe piles and can coordinate the progress of construction work.
