摘要

通过建立不同找平系统的传感器在横向弯道和纵向上、下坡道上的探测模型, 得到具有一定扫描长度的找平系统对一段给定路基的扫描将改变其浮动平均高程的定性趋势, 以及相应情况下采样长度与浮动均值之间的数值定量关系, 证明了曲线路面的曲率半径越小且采样长度越大时, 找平系统所获得的浮动均值偏离基准点高程的程度越大。研究结果表明:在实际使用中, 应根据曲线路面曲率半径的大小、路面横向弯道的超高率容许误差和路面厚度容许误差范围合理选择找平系统的采样长度。

Abstract

Through setting up the detecting models of sensor of different leveling systems in horizontal curve and vertical upgrade and downgrade curved road, authors gained that the scanning of leveling system with a sampling length would change the floating mean altitude of a section of given road basis and gained the qualitative trend and the numerical relationship between the sampling length and the floating mean value. It proved that the difference between the floating mean value and the benchmark on the curved road was proportion to the sampling length and was inverse proportion to the radius of the curved road. The results show that it is essential to select a sampling length reasonably according to the radius of the curved road, the allowed offset in superelevation and allowable thickness error when using sampling length of the leveling system.
