Abstract Research purposes:With the developments of science and technology，the analysis methods for paaial test items stipulated in”Code for Rock and Soil Chemical Analyses for Railway Engineering”issued in 1987 fall behind the current chemical analysis method and test technology．So it is necessary to revise the code for meeting the demands of railway construction．
Research conclusions: In this paper．the introduction iS given to the main revised contents and the issues for caution on implement of the revised”Code for Rock and Soil Chemical Analyses for Railway Engineering”
