Abstract:
The inner guy wire is an important component for the gin pole used in the erection of 370-meter high tower. Due to the large leg span and heavy single component of the high tower, the high speed wind environment throughout the year caused by the high towers location in island and high operating height of the gin pole, it is shown from the analysis and the calculation that setting the inner guy wires with four groups will cause the inner guy wires bearing excessive force which lead to a great difficulty in the construction, low anti-twist characteristics and serious deflection of the gin pole. Therefore, the anti-twist inner guy wires with 12 groups are innovatively used in the tower erection based on the finite element analysis and tests of the gin pole. The successful application of this new method in the erection of Zhoushan 370-meter high tower provides a new way to set inner guy wires for similar projects.
