Distinguishability of engineering settlement and land subsidence in the settlement evaluation of high-speed railways

SHANG Jin-guang①,ZHANG Xian-zhou①,GUAN Chao-wei②(①Dept.of Surveying Engineering,Southwest Jiaotong University,Chengdu 610031,China;②Chengdu Institute of Surveying and Investigation,Chengdu 610081,China)  
The Beijing to Jinan section of a high-speed railway is located in the Northern China Plain,along with different degrees of land subsidence.For the railway through the different sections of different land subsidence,the settlement observed is the comprehensive expression of land subsidence and engineering settlement.As the rate of land subsidence is not uniform in space,the paper studied to distinguish between the land subsidence and engineering settlement,and gave the improved observation method as solution.
