地铁轨道工程铺轨基标的测设方法

Surveying Method For The Track Laying Benchmarks of Subway Track Engineering

结合广州地铁二号线轨道工程 ,介绍了怎样保证地铁轨道工程铺轨基标 (控制基标、加密基标和道岔铺轨基标 )测设精度的作业方法。

In Combination with the NO.2 line track works of Guangzhou Municipal Subway Track Project,this paper introduces the operation method,the technoligical process and some notice to ensure the survey accuracy on the track laying benchmarks (control benchmarks,additional benchmarks and benchmarks for track switches)
