摘要:

探讨一种在施工场地狭小、通视条件差的条件下进行施工测量放线的方法——角度交会法。通过对前方测角交会法和后方测角交会法测量中误差的理论分析并结合工程实例证明使用全站仪以避雷针等尖状地物作为测量控制点进行施工测量放线时,在合理选择布点位置和设站位置的条件下可以满足施工精度要求。

Abstract:

The spatial angle intersection method in limit field and under bad visibility environment is discussed. The monitoring errors of spatial angle intersection method and azimuth and elevation method are theoretically analyzed. It has been proved that the construction precision can meet the requirements when choose the rational positions of layout points and stations using total stations.

Key words: total station, surveying, forward intersection, backward intersection, error propagation, precision analysis
