A discussion of multi-segments networking of CPII control network in the long high-speed railway tunnels
摘要
Abstract
The current high-speed rail measurement specifications stipulated that CPII control network of Ballastless track in the tunnels should be completed by one time after tunnel holing through. However, some of the CPII control network in the long high-speed railway tunnels have to divide into Multi-segments due to the tight construction. In this paper, the application was illustrated by the example of Baofeng tunnel-CPII control network for three segments, and the measurement technology of multi-segments networking of tunnel-CPII control network was put forward. Using the hybrid structure network that consists of free-station linear-angular intersection network and crossover traverse network mentioned in the paper and the technology that overlapping data no error handling, the tunnel-CPII control network of meeting the requirement of precision was established. On the other hand, this project also can avoid the risk that lap error is large and difficult to deal with when each segments constructed respectively. So, the solution is worth applying on the CPII control network in the long high-speed railway tunnels.关键词
