As the main hoisting equipment of full container yard,rail foundation of rail-mounted gantry crane (RMG) is sensitive to settlement and differential settlement of the foundation.At present,in China,the standard method is mainly used to calculate and analyze the foundation settlement based on the exploration and indoor geotechnical test data.Cone penetration test (CPT) can reflect the in-situ physical and mechanical properties of soil,and has the advantages of fast test speed and high economic benefits,so it is widely used in the evaluation of ground improvement abroad.On the basis of cone penetration test data of hydraulic fill sand ground of container terminal project in Middle East,the internationally recognized Schmertmann method is adopted to analyze settlement and differential settlement of rail foundation.The calculation results of the engineering examples show that the analysis results of the settlement calculation method of the track foundation based on CPT data meet the international design standards of the rail foundation,and the research results can provide a reference for similar overseas project design.
