摘　　要：基于对国内建筑住宅室内振动监测与评价方法的分析与探讨,表明室内振动测量相关技术要求基本一致。评价量不同,数据处理与评价方式不同,造成仪器技术性能要求不同。GB/T 5035—2005不适用于环境保护领域室内振动的监测,其标准限值较宽松。JGJ/T 170—2009是针对地铁引起建筑物室内振动监测与评价的方法,且需满足GB 10070—1988的限值要求,其评价量应包括VL_(max)与VL_(Zmax)。但JGJ/T 170—2009与GB 10071—1988规定的振动测试频率范围与频率计权因子完全不同,为便于评价应尽早统一振动测试的频率范围和频率计权因子。VL_(max)与VL_(Zmax)的大小无法简单判定。Based on analyzing and discussing on domestic monitoring and evaluation methods of indoor vibration, results showed that the technical requirements of indoor vibration measurement were basically consistent. Different evaluation indexes had different data processing and evaluation methods, and the performance requirements of the instrument were different. GB/T 50355--2005 could not be apply to monitor indoor vibration in the field of environmental protection, and its standard limit was more relaxed. JGJ/T 170--2009 was a method for monitoring and evaluating the indoor vibration of buildings caused by subway, and it needed to meet the requirement of GB 10070-1988＂s limit, so its evaluation indexes should include VL（Zmax） and VLZmax. However, the vibration testing frequency range and the frequency weighting factors of JGJ/T 170-2009 was completely different with GB 10071-1988＂s. In order to facilitate the evaluation, the vibration testing frequency range and the weight factors should be unified as soon as possible. The size of VLmax, and VL（Zmax） were not easy to determine.
