摘　　要：针对地铁列车引起的建筑物二次辐射噪声进行了现场试验研究和评价量的探讨分析。从多个角度对试验数据进行了分析,总结了运行列车引起的室内二次辐射噪声特性。从分析频谱宽度、分析时间长度和背景噪声等几个方面研究了影响建筑物室内二次辐射噪声评价量的若干因素,并探讨了不同评价量之间的相关性以及中国现行标准中使用的评价量存在的不足。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.
