Abstract:Research purposes: At present,the absolute survey method of the electronic total station ( ETS) is used for the precision adjustment of the ballastless track regularities. With this method,by surveying the external geometric state,the internal geometric state is controlled,but it is not fully compatible with the traditional concept of track irregularities. In this paper,the discussion is made on the error of absolute survey and the analysis is made for the control precision of this precision adjustment of the ballastless track irregularity.
Research conclusions: The theoretical analysis and relevant experiments proved that using the adjustment method of absolute survey with high accuracy ETS could meet the accuracy requirements of within ± 2 mm for the horizontal irregularity adjustment of the ballastless track of high - speed railway.
