According to the municipal engineering construction the characteristics of deformation monitoring, through five period with precision WanJi·OuJun of qingtian county retaining wall's estate horizontal displacement and subsidence data results, the design is mainly through the field, the county to WanJi manor retaining wall in the construction stage to wall (slope) of deformation observation. In the deformation analysis process, choose the level of horizontal displacement monitoring data and the analysis of the data test. First data are singular value inspection, next to the deformation data periodic never get periodic data for the original data of the comparison of the interpolation method, and finally wit...
