Experimental study on deformation and strength characteristics of granular soil-structure interface under coupled monotonic shear and vibration using a modified direct shear apparatus

Soil-structure interaction under vibration becomes an important concern for the underground structure below or adjacent to a railway line as train speed is continuously raised. Although more and more related works have been conducted in recent years, the vibro-induced soil-structure interaction is not fully understood, especially for high-frequency vibration. By using a modified direct shear apparatus with a high-frequency vibration module, …
