摘要:近年来,市政道路交通导致邻近区域的环境及建筑物产生过量振动,严重影响邻近居民的学习工作和生活本文通过选择某城市具有代表性的典型市政道路开展振动实测,通过对实测数据的统计分析,获取不同测点的振动加速度、频谱特性及振动衰减规律。结果表明:某城市典型道路引发的环境振动主频段为8~16Hz,主要以中低频振动为主;随着至道路的距离不断增加,振动强度呈显著下降趋势,但衰减幅度趋缓;车重是影响道路环境振动的重要因素;在某城市典型场地条件下,道路交通振动影响范围约为道路周边20m。
Abstract: In recent years,municipal road traffic has caused excessive vibration in the surounding environment and buildings,seriously affecting the leaming,work, and life of nearbhy residents. This article conducts vibration measurement on representative municipalroads in a certain city. Through statistical analysis of the measured data, the vibration acceleration, frequency spectrum characteristics, andvibration attenuation law of different measurement points are obtained. The results show that the main frequency range of environmentalvibrations caused by typical roads in a certain city is 8-l6Hz, mainly consisting of medium to low frequency vibrations; As the distance tothe road contimues to increase, the vibration acceleration shows a significant downward trend, but the attlenuation amplitude slows down;Vehicle weight is an important factor affecting road environmental vibration;Under typical sie conditions in a certain city, the impact rangeof road traffic vibration is about 20m around the road.
