Research on installation and measurement technology of double I-shaped steel plate composite beam
双工字钢板组合梁安装测量技术研究

摘要

随着社会的进步，传统桥梁设计不能满足社会发展需要，因钢板组合梁构造简单、制作与施工比较容易，得到了广泛应用，其中安装控制是钢板组合梁施工的关键环节。为了确保钢板组合梁安装后符合设计要求同时达到外形优美，测量工作尤为重要。钢板组合梁的安装位置及标高控制是测量工作的重中之重，其三维坐标定位为测量重点。

Abstract

With the progress of society, the traditional bridge design cannot meet the needs of social development. Due to the simple structure of steel plate composite beams, the production and construction are relatively easy, and they have been widely used. The installation control is the key link in the construction of steel plate composite beams. In order to ensure that the steel plate composite beam meets the design requirements and achieves a beautiful appearance after installation, the measurement work is particularly important. The installation position and elevation control of the steel plate composite beam are the top priority of the measurement work, and its three-dimensional coordinate positioning is the focus of the measurement.
