In-situ experiments and investigation of evaluation indexes were performed to study the subway-induced ground-borne noise in buildings along the subway lines .The characteristics of ground-borne noise in buildings were summarized from various aspects by analyzing the experimental data .The factors such as the spectrum width ,the analyzing time and background noise effect on the results of evaluation indexes , were further investigated . The correlation between different evalution indexes was analyzed , and the deficiencies of the indexes of noise evaluation in the environmental noise control codes of China were discussed .
