桥梁后张法施工单端张拉工艺控制

The One-end Tension Process Control in Post-tensioning Bridge Construction

桥梁工程现浇或预制后张预应力梁张拉锚固体系的质量控制,关键是原材料的选用与施工工艺控制。本文结合佛山市顺德区快速干线网首期工程SJ5合同段高赞立交(主线桥)工程实例,重点介绍桥梁后张法单端张拉施工工艺控制。

Bridge engineering in-situ or precast post-tensioned beam tension anchorage system of quality control, the key is the selection of raw materials and construction process control. In this paper, Shunde District, Foshan City, the first phase of rapid telecommunications network SJ5 Contract Section KO Interchange (mainline bridge) project, this paper introduced a single-ended post-tensioned bridge tensioned construction process control.
