An Improved Apparatus for Testing the Friction Variation of Soil-Structure Interface Induced by One-Dimensional Vibration

Forced vibration of underground structures is a common activity during the construction or service period of rail infrastructure, such as vibro piling, the vibration of piles, and tunnel lining under moving train loads, etc. To better predict the structure's performance under vibration, a lot of attention has been paid to investigating the behavior of interfaces between soils and structures. However, limited by the capabilities of the current …
