Analysis of Environmental Vibration and Indoor Secondary Structure Noise of Planned Plots around a City Subway
This study investigates the environmental vibration and indoor secondary structural noise effects of a certain city's subway on its surrounding planned plots.The planned plot is adjacent to the transfer stations of Line 3 and Line 5 of the subway,and the planned residential buildings within the plot are respectively affected by the two subways of Line 3 and Line 5.The ground vibration of typical residential buildings during subway passage was monitored and the indoor secondary structural noise was calculated according to the prediction method in the Technical Guidelines for Environmental Impact Assessment-Urban Rail Transit.Analysis shows that the individual impact of Metro Lines 3 and 5,as well as the combined impact of two subways,can meet the relevant standard requirements.The vibration impact generated by train braking is greater than that generated by trains in the low-speed range of 30km/h.Under the same train operating condition,the impact of environmental vibration and secondary structural noise shows a decreasing trend with increasing distance.
