Abstract: 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.
