Vibration Assessment of Subway Line 2

Project Overview
  • A new building is planned near the operation section of Subway Line 2.
  • Review of vibration and structure-borne noise within the office facility caused by subway operation.
  • Comparison with recommended vibration/noise criteria and application of anti-vibration measures if exceeding limits.
  • Application of anti-vibration measures using HD-MAT-50T (Slurry Wall method applied).
  • Vibration/noise levels satisfied recommended criteria after implementation of anti-vibration measures.
