基于公路桥梁施工控制测量中GPS的应用

Application of GPS Based on Highway Bridge Construction Control Survey

在我国公共设施项目建设中,公路桥梁施工是不容忽视的重要方面,在我国经济等方面不断发展的背景下,其相关的施工技术水平也有了较大的提高。在过去工程进行测量时,由于全站仪等相关技术设备的应用,从而实现了工程建设的精确度测量,但是,对于一些野外测量工程来说,其测量过程中很难具备精确度的要求。随着时代的不断发展,出现的GPS技术,对公路桥梁施工控制测量工作有了较大的帮助,不仅促使工程具备精确度的要求,而且更是给施工人员带去了诸多工作的便利。分析公路桥梁施工测量控制内容及控制的主要部位,介绍GPS系统在公路桥梁施工控制测量中的应用。

In the construction of public facilities in China, road and bridge construction is an important aspect that can not be ignored. In the context of the continuous development of China＇s economy and other aspects, its related construction technology level has also been greatly improved. In the past, the precision measurement of engineering construction was realized because of the application of the total station instrument and other related technical equipment. However, for some field measurement engineering, it is difficult to have the requirement of accuracy in the measurement process. With the continuous development of the times, the emergence of GPS technology, the highway bridge construction control measurement work has been greatly helped, not only to promote the accuracy of the project, but also to the construction staffwith a great deal of work. This paper analyzes the content and main parts of highway bridge construction survey control and introduces the application of GPS system in highway bridge construction control survey.
