摘要：
The most relevant static detection data with the ride quality of high-speed railway is its long-wave data. Among all the long-wave measurement methods, the semi-observation method of relative survey has the best engineering practicability if its long-wave accuracy can be improved. The factors that influence the long-wave accuracy of the semi-observation method were studied, and the real-time earth-rotation compensation model was founded and its effect was verified in the paper "Study on Improving Accuracy of Track Long-wave Irregularity Measured by Semi-observation Method(Ⅰ)", which just performed the real-time compensation according to the line design data. This kind of semi-observation method based on the design attitude to compensate for the rotation of the earth was limited by the availability of design data, and its accuracy can not be guaranteed when the actual deviation from the design was large. Therefore, this paper continued to develop the semi-observation method compensated by using the real-time attitude of the track detector, whose method of using attitude-angle increments to calculate the long-wave was more reasonable than before. The experimental results show that the precision of the method based on real-time attitude compensation is higher than that based on design attitude compensation, especially when the line deviation is large. © 2021, Department of Journal of the China Railway Society.
