MONITORING OF VIBRATIONS FOR THE CONSERVATION OF CULTURAL HERITAGE：THE CASE OF THE SUMMER PALACE IN BEIJING

Abstract. In order to research the influence of the environmental vibration and the protection of the architectural heritage, CMG-5TCDE accelerometer was used to obtain the real-time vibration monitoring data of the Grand Stage in the Garden of Virtuous Harmony in Summer Palace. This paper employs the control variable method and the multivariate statistical analysis, integrating monitoring statistics with wind speed and transportation observation statistics to make interrelated analysis, in order to study the response rules and impact degree of the Grand Stage under the environmental vibration impact. The analyses of the vibration monitoring statistic of the recent two years show that the vibration acceleration of the Grand Stage is below 10mm/s², which is remarkable related with factors such as visitors flow rate, transportation and weather.
