摘要
文章结合鳬洲大桥的场地特点,有针对性地进行技术方案设计,并对采用测距三角高程测量法实施二等跨河水准测量的误差来源进行分析,采取相应的措施和手段,有效消除和减小了误差项的影响,取得满意的效果。
The paper introduces the river - crossing leveling technical programme of the Fuzhou Bridge and analyses the error sources about second order leveling replaced by triangulated height sui＇veying. The article gives out appropriate measures and means to eliminate and reduce the impact of the errors and get satisfactory results. The content and conclusion of this paper has consulting meaning and practicable value for similar projects.
