Abstract:A typical roadbed section of an inter-city high-speed railway was selected in Shandong Province as the research object,andthe settlementof sandstone embankment was predicted. Elastic modulus was selectedas the main factors to derive a empiricalformula to be used in practical engineering, making up for the weakness of the existing theoretical prediction methods.
