摘要
传统监测方法对长距离多幅线性高架桥梁,具有作业效率低、数据处理较为烦琐等难点。为有效提高长距离多幅线性高架桥梁监测作业效率,文中提出一种基于GNSS和导线测量布设水平位移基准网的方向观测法。该方法具有施测难度低、建立统一坐标系方便、后期数据处理简易等特点,并以福州环岛路第一标高架段工程为例,验证了此方法的高效性。
The traditional monitoring method for long distance multi-linear overpass has some difficulties,such as low working efficiency and complicated data processing.In order to effectively improve the monitoring efficiency of long distance multi-span linear overpass,a direction observation method based on GNSS and traverse survey layout of horizontal displacement reference network is proposed.This method has the characteristics of low difficulty in measuring,convenient to establish a unified coordinate system,and simple data processing in the later stage,etc.And taking the first elevated section of Fuzhou Huandao road as an example,the high efficiency of this method is verified.
