Effect of Underground Metro on Historical Monuments in Delhi

摘要

Today, traffic induced vibration control is a frequently used concept for enhancing the living standard in residential apartments along railway lines. Vibrations generated by metro train running on underground tracks transfer through the ground into surrounding structures. These traffic induced vibrations usually cause no threat to the safety of the structures, but their undesirable impacts can significantly lower the quality of life and the working conditions of these structures. Traffic induced vibration in the buildings due to metro trains have been analyzed by using 1/3 octave analyzer. The results obtained were compared with Federal Transport Authority guidelines and its effects on nearby structure have been investigated. This study involved collection of vibration data for five historical monument located just above the metro tunnel on the corridor of Delhi Metro. It was concluded that the vibration level (VdB) at each location is well above the permissible level of vibration recommended by various standard authority. The maximum value out of five historical monuments found at Darya Ganj was 104.6 VdB.
