软横跨结构抬高调整计算方法

COMPUTING METHOD OF LIFTING ADJUSTMENT OF SOFT LATERAL SPAN STRUCTURE

本文针对京广线既有软横跨接触悬挂抬高施工过程中,在不加高软横跨支柱高度前提下,对横向承力索直吊弦缩短量和横向承力索缩短量进行简化计算,提出了适合现场的具体计算方法。

This simplified computing is made on the shrinkage of lateral catenary and its straight hanger and the suitable concrete computing method is proposed for the construction of lifting existing soft lateral span contact suspension without lifting the hehght of soft lateral span supporting pillar.
