The Application of Deep Foundations to Mitigate Ground Vibration for a Train-Supporting Viaduct Structure in Soft Ground Area

摘要

The ground vibrations induced by high-speed train have drawn engineering attention in recent years. Many influences have to be considered to decide the vibration mitigation scheme. For the train-supporting viaduct structures, the foundations were found to be one of the key factors governing the amplitude of vibration level for the nearby ground area. An overview of these topics with numerical prediction analysis and practical vibration measurement which were conducted based on Japan SKS and Euro-Star high-speed train are presented in this paper.
