谈既有铁路线路复测中一种改进的中平测量方法

An improved method for center stake leveling in repetition survey of existing railway

结合水准测量方法中的双转点法和四等水准测量方法,提出了一种改进的可用于普通的既有铁路线路复测的中平测量方法,并分析了该方法的可行性,指出其在满足测量精度要求的前提下,提高了工作效率。

Combining with twin turning point method and fourth-grade-leveling method used in leveling methods,the paper puts forward a new feasible center stake leveling method in existing railway repetition survey,analyzes its feasibility,and finally points out that,it improves the working efficiency in the premise of meeting measurement accuracy.
