| Abstract: | This paper describes the implement method of level surveying in the settlement monitoring of Jiaoxin railway in the whole. Firstly, it introduces the general situation of Jiaoxin railway as well as the purpose and the contents of this survey. Secondly, it describes the principle and method of survey. It emphasizes the data treatment theory and method,including the probing of abnormal data and Coarse Adjustment treatment as well as the Least Square Method and Robust Estimation. Finaly, this paper emphasizes the application of Fourier Analysis in the survey. |
