摘要
传统码头圆桩放样一般通过两至三台经纬仪用视线交会的方法来实现,因而存在效率低、精度不高等问题。本文利用一台全站仪通过观测桩身不在同一直线上的4个点实现圆桩的快速高精度放样,经由实际观测数据,验证模型的正确性。
Sight intersection is the traditional method for circle pile lofting by two to three theodolites.It has disadvantages of low efficiency and fuzzy precision.This paper use a total station by observing four points not in a straight line to achive circle pile lofting of high precision and efficiency.Through actual observation data,correctness has been verified.
