| Abstract: | The precision and reliability analysis of points in settlement monitoring network is an important factor to guarantee the accuracy of deformation process data. Using the three adjustment model, this paper compared the precision of observation datum network. Combining a practical example, this paper brought forward a solution of network which is based on selecting Quasi - stable adjustment method and can deal with soft ground case. |
