| Abstract: | Three‐dimensional adjustment data processing method of the total station observation data is introduced ,based on linear‐angular intersection measurement network in monitoring of foundation pit . Through an engineering example ,the method is validated that can meet the monitoring accuracy of the secondary excavation by the accuracy analysis , so deformation information is fed back accurately and efficiently . |
