轨道长波不平顺半测回法测量精度的研究(Ⅰ)
|
摘要
与高速铁路平顺性最相关的静态检测数据为其长波数据。在各种长波测量方法中,相对测量中半测回法的工程实用性最好,但其长波测量精度亟待提高。本文研究影响半测回法长波测量精度的因素,测量中地球自转分量未得到完全补偿是造成其精度偏低的主要原因,提出对半测回法进行实时地球自转补偿的数学模型。在现阶段的试验中,根据线路设计资料对半测回法进行实时补偿,较好地修正了地球自转补偿不完全带来的误差,令半测回法的长波误差回到容许值(3 mm)以内。研究表明,进行实时地球自转补偿在提高半测回法的长波测量精度上是实用有效的。
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 will have the best engineering practicability if its long-wave measurement accuracy can be improved. In this paper, based on the analysis of the factors that influence the long-wave measurement accuracy of the semi-observation me-thod, and the consideration on the incomplete compensation of the earth's rotation component in the measurement as the main reason for its low accuracy, a mathematical model for its real-time earth-rotation compensation was proposed. In the current experiments, real-time compensation was made to the semi-observation method according to the line design data, which corrected the error induced by the incomplete earth-rotation compensation, and returned the long-wave error of the semi-observation to the allowable value within 3 mm. The study indicates that the real-time earth-rotation compensation is effective and practical in improving the long-wave measurement accuracy of the semi-observation method.
