Abstract
With reference to the roadbed construction of the section DK109 + 800 - DK110+ 150 on Harbin-Dalian Passenger Dedicated Line, this paper discusses the use of PTK survey technology and 3DGPS system to ensure real time control of roadbed paving thickness, smoothness and slope gradient, and the employment of CCS900 compaction system to realize real lime monitoring of roadbed compaction to guarantee the accuracy of roadbed geometries and improve work efficiency.关键词
