Abstract:
Through analyzing the impact factor and error recourse of surveying data during the construct-control of main cable of the suspended-cable, this paper introduces a surveying method and a corresponding adjust scheme. The basic rope lineari- ty survey of main cable can not use leveling. Because a high precision omnipotence instrument can survey in one direction, it is difficult to collate if it exists error. At the same time, the basic surveying rope is very sensitive to the change of tempera- ture, magnitude wind and the offset of the tower. So the adjusting to the surveying scheme is necessary to satisfy the preci- sion requirement. Such as selecting the non-wind or little wind weather, selecting the night surveying due to the steady tem- perature, using two high precision omnipotence instruments at the same time etc.
