Study on Assessment Models for Analysis of the Adverse Effects of Railway Vibration on Residential Area
철도 진동에 대한 위해성 평가 모델 연구
Abstract
This paper introduces what amount of railway vibration level observed from residential area. Five residential area located near the railway were selected to measure the vibration levels generated by the different types of Korean railway vehicles. Those 3-axis vibration measurements are applied to the frequency-dependent weighting functions recommended by ISO 2631-2, which are used to evaluate the 3-axis combined vibration levels such as peak levels, L 10 levels and root-mean-squared values. These evaluated results are shown to indicate the environmental vibration severity for the different residential area. In addition to those physical vibration measurements, the survey of subjective responses of residents was also carried out by distributing the questionnaire suggested by WHO. The questionnaire includes the subjective scales for assessing the annoyance and the sleep-disturbance caused by the environmental vibration. The statistical analysis results collected from 386 respondents are introduced. The highly annoyed population and the highly sleep-disturbed one are examined to identify the .elation between their subjective scale and their corresponding environmental vibration levels. These attempts are shown to lead to the salient model to relate the environmental vibration level and the subjective responses of Korean residents to annoyance and sleep-disturbance.
