摘要
阐述了静力水准沉降自动化观测系统的工作原理和安装注意事项,并提出了对高程进行平差后处理的一种计算方法。通过两套超长线路、超大高差、超多转点、超多测点的自动化观测系统实例,对各项观测指标进行了精度估算;并根据阶段自动化监测结果与人工监测结果的比较,对平差方法进行了验证,平差后的自动化监测结果与人工监测结果吻合度更高,有效提高了自动化观测结果的可信度。
In this paper,the principles and installation precautions of the automatic settlement observation system with a long hydrostatic level are described in detail,and an adjustment method for data post-processing is proposed.The accuracy of every observation index in two sets of automatic observation systems with a long routine with large elevation differences,excessive turning points and measuring points is estimated in the paper.The adjustment method could be verified by comparing the staged automation results with the manual survey results.After the adjustment,the results are more consistent with the manual survey results.This method effectively improves the reliability of settlement automatic observation results.
