Analysis of Influencing Factors on Environment Vibration Induced by Metro Transit and Fuzzy Comprehensive Evaluation
Abstract:
To assess the effect of environmental vibration induced by metro transit, a fuzzy comprehensive evaluation was conducted. First, a three dimension bridge-soil-building FE model was established using the parameters from a practical engineering, and the time-history loads were utilized to analyze the vibration in the nearby buildings. Second,a questionnaire survey was conducted based on which the human body comfort effect factor and its weight were determined. Last, the fuzzy comprehensive evaluation was conducted combined with the results of the FE analysis and the questionnaire. The evaluation results show a high consistence with the fact, indicating that the fuzzy comprehensive evaluation is a effective method to evaluate the effect of environmental vibration to the human body.
