摘　　要：将声强法应用于3种不同类型的高速铁路声屏障的隔声测量中,并与声压法的隔声测量结果进行对比分析,讨论声强法在高速铁路声屏障隔声测量中的优势。研究结果表明:声强法能直观的检测出声屏障存在的漏声点;能为高速铁路声屏障的精细设计提供支撑;为高速铁路异型声屏障测量、现场隔声测量提供依据,并为高速铁路声屏障相关设计标准的修订提供数据支撑。研究成果对高速铁路声屏障隔声测量具有一定的指导意义,能为现场隔声测量提供可行方法。The sound intensity method was introduced in the measurement of sound insulation of three different types of high-speed railway(HSR)sound barriers.The comparison was made between the sound pressure and sound intensity methods,and the advantages of sound intensity method in the sound insulation measurements of HSR sound barriers were discussed.The application results of the three different types of HSR sound barriers show that the sound intensity method can detect the leakage points of sound barriers more intuitively than the sound pressure method.The findings could provide technical basis and reference for the fine-tuned design of HSR sound barriers,the measurement of irregularly shaped HSR sound barriers,and the measurement of field sound insulation.It also provides measurement data to support the revision of relevant design standards of HSR sound barriers.This study can provide significant guidance for the sound insulation measurement of the HSR sound barrier and provide feasible methods for the measurement of field sound insulation.
