Study On The Waterborne Piling Model

This thesis set down one whole scheme processed piling and position above water , which adopted the RTK of GPS and combined range finder free of lens with the requirements of piling and position above water of large piers and bridges construction nowadays.The studying in the coordination system and the transition between them referred in the using GPS-RTK to pile to make orientation has educed the technique of establishing ship coordination system and determining transition point, by adopting the orientation pattern which a range finder is existing or not, to make the mathematics model of computing stake center coordination and stake-top elevation of designing elevation surface.The detailedly analyzing to the hammering in time-domain and frequency-domain has deduced two kinds of methods to identify the count of hammering by Clustering Analysis to obtain the hammering signal characteristic, one is characteristic identifying method and another one is statistical identifying method that is better in antinoise than characteristic identifying method and full of practicality.
