路面交通诱发的振动对邻近地下遗址的影响
Effects of road traffic-induced vibration on adjacent underground ancient ruins
摘要
Abstract
In order to study the influence of road traffic-induced vibration on adjacent underground ruins,and accurately define the safe distance between them,a field test was carried out on the vibration of underground ruins caused by traffic load at Chengshang Village ruins in Jurong City.Based on statistical analysis of test data,the vibration velocity as a function of driving speed and vibration source distance was derived.Results showed that the superior band of the vehicle load was 0-40 Hz,and high-frequency vibration decayed faster that of low-frequency vibration.The vibration velocity was positively correlated with travel speed and exponentially decayed with the distance from the vibration source.Under the certain load and vibration velocity limits,the safe distance increased with the increase of driving speed,so the speed limit needed to be considered when determining the safe distance of cultural relics.The research results could predict the vibration response of underground cultural relics,and the conclusions could provide reference for traffic planning and protection of underground cultural relics.关键词
