Abstract：Abstract ： Research purposes ： The current product standard of geocell cannot satisfy the construction requirement of railway engineering，and it is necessary to establish the professional standard according to the characteristics of railway engineering. The functional requirements of railway engineering and performance indexes of product are closely combined in the process of standard establishment. Systematic research about product performance index should be proceeded in order to determine the engineering applicability of different products. Research conclusions：( 1 ) The new performance indexes of tear resistance， tensile strength between geocell slice， suspended loading time and uvioresistant percentage retained strength of node are put forward in the new standard，and reflect theproduct performance more comprehensively. (2) There are large differences of performance index between different geocell products according to the test results， the applicable products for foundation treatment， subgrade reinforcement and slope protection in railway engineering are proposed. ( 3 ) The establishment of railway industry standard unifies the product name and performance index， makes the production company and design， construction， supervision departments in railway engineering refer to, and specifies the application of geocell in railway engineering.
