特大跨径悬索桥主缆PPWS施工牵引力近似计算方法
Approximate calculation method of main cables PPWS construction traction force for extra-large span suspension bridge
摘要
Abstract
For the large number of wire strands and the long distance of strand traction, the wire strands arc erected normally with gantry pulling traction system that allows continuous pylon passing in the construction of main cables with PPWS(prefabricated parrel wire strand) method for an extra-large span suspension bridge. The accurate calculation of traction force is of realistic significance to the selection of traction equipment and ensuring smooth construction. In early days of suspension bridge construction, the capacity demand and type of traction e-quipment were determined mainly based on experience. In this article, exploration was made for the traction force calculation method of the gantry pulling traction system for PPWS construction, and the results were compared with measured data on work site. It proves that the calculation result is reliable and can be used in construction calculation.关键词
