【摘要】 介绍全站仪三维自由设站进行基坑监测的方法。根据三维自由设站的测量原理,利用高精度全站仪通过测站的水平方向、天顶距、斜距观测值完成三维自由设站进行基坑监测点的三维数据的采集。通过结合工程实例,进行设站精度分析,并比较三维自由设站与传统方法比较,以验证结果与模型的准确性。更多还原

【Abstract】 The method of foundation pit monitoring with three-dimensional free station of total station is introduced. Through the observation values of horizontal direction, zenith distance and slant range of the station, the three-dimensional data collection of the foundation pit monitoring point is completed by three-dimensional free station with high-precision total station.By combining an engineering example, the accuracy of the station is analyzed, and the three-dimensional free station is compared with the traditional method to verify the accuracy of the results and the model.更多还原
