Abstract
Under the guidance of the country's major strategy of " The Belt and Road" and for the purpose of promoting the acceptance and recognition of Chinese standards by other countries,this paper conducts a systematic analysis of the classification criteria of the German railway geotechnical classification,the type of filler,the filling site of the filler,the compaction index and the standard of roadbed packing with reference to the design of the subgrade of a railway in Libya,and compares them with the Chinese railway standards.It is concluded that the main difference between the classification of geotechnical and subgrade filling of Chinese and German railways is the difference between the uniform classification and the particle size accumulation.The difference in the foundation of bedrock is mainly the difference between the single layer and the multi-layer,and the compaction index and the standard of subgrade are much the same.These differences and similarities are of great significance to the design of subgrade fillers in overseas railway projects subject to German standards.关键词
