Positioning Survey of Anchor Padding Plates and Cable Ducts of Cable-Stayed Bridge Without Backstays

锚垫板与索道管定位是斜拉桥施工过程中精度要求很高的测量工作。介绍孝襄高速公路孝南互通立交无背索斜拉桥主塔锚垫板、索道管的空间直线定位原理,施工测量方法及精度分析。

The positioning survey of anchor padding plates and cable ducts is a kind of survey work requiring very strict precision in the construction of a cable-stayed bridge. This paper presents the spatial straight alignment positioning principles, construction survey methods and survey precision analysis of the anchor padding plates and cable ducts in pylon of the cable-stayed bridge without backstays of Xiaonan Interchange on Xiaogan-Xiangfan Expressway.
