摘要
文章结合工程实例,综合传统测量方法与现代测量技术,详细介绍了一套实用、高效的斜拉桥索塔施工测量放样方案,提出了"立面放样、由线定面"、"以测代放"等一系列全新思路,较好地解决了厦门枢星桥独特的倒Y型双向倾斜索塔的施工测量放样问题,不仅保证了每节段模板的定位精度,确保索塔线形满足要求,而且大大提高了工作效率,可为类似工程施工测量提供有益的参考。
A practical and high efficient construction survey method for bridge tower is proposed based on traditional measuring methods and modern measuring technology. The new ideas of this method can be summarized as ＂elevation setting--out, surface determined by lines, setting--out replaced by surveying＂, with which the problems in construction, measuring and layout of the u- niquely inverted Y--shaped ＆ two--way inclined tower in Xiamen Shuxing bridge were well solved. This method not only ensured the location accuracy for each formwork to meet the requirements for the line shape of the tower, but also greatly improved work efficiency. Therefore this method is a good example of similar projects.
