long-span bridge management system of linear

摘要

The present invention is a linear long-span bridge to accurately measure the position coordinates of the element needed for linear control of long-span bridge relates to a linear control system of the long-span bridge that enables the administration. ; To this end, the present invention has an upper pylon position information from the GPS satellites in the collection device installed in the main tower top and the front end of the long-span bridge receiving each of the position coordinate data and position coordinate data of the distal end, provide the received data to the linear coordinate position management unit that is installed on the reference point and the position coordinate data of the main tower provided with position coordinate data of the upper front end geometry control system applies each of the measurement error is obtained by comparing the position of the reference point coordinate data received from the GPS satellites and the position coordinate data of the group reference point measured according to the measurement method to separate the upper part of the pylon position coordinate data and position coordinate data of the distal end After adjustment to the upper portion of the pylon position coordinate data and the position coordinate data of the front end, the upper part of pylons calculated corrected position coordinate data and the coordinate data using the location of the front end if did occur to some extent separated from the target linear tension to the cable can be configured to calculate the value. ; Accordingly, the present invention is as able to use the DGPS measurement techniques to accurately measure the position coordinates of the pylon top and front end, long-span bridge under construction this goal able to be calculated from the linear extent shone out how to calculate the number of political tension in the cable and, thereby, the more efficient it becomes possible to perform a linear management of long-span bridge.
