Abstract Abstract : Research purposes : In order to perfect subgrade design technical standards of high speed railway，according to China Code for Design of High Speed Railway ( TB 10621 -2014) and Germany railway industry standard 5otechnical Structure and Geotechnical Engineering Design，Construction and Maintenance ( Ril^836 -2013 )，comparison and analysis works were done from six aspects : design philosophy， computational load， subgrade structure， subgrade filling and compaction standard，standard of post - construction settlement. The differences for main technical standards of high - speed railway subgrade between China and Germany were put forward. Research conclusions :( 1) Most of the requirements in Germany and China railway technical standard are same，but the design idea in local content are different. (2) Parameter values of Germany and China railway main technical standard are almost same，China standard still need supplement and perfection. (3) Design idea of protect layers put forward by Germany can be used for studying the general design metliod of roadbed in China.
