Experimental Study of the Effect of Vibration on the Shear Strength on the Interface Between Concrete and Bedrock for a Project

This report studies the effect of vibration on shear strength on the interface between concrete and bedrock, which is prepared for Gezhouba Dam key water control project. A set of in-situ tests were carried out in the following way: the vibration load was applied besides the statically load and shear tests were conducted in the course of vibration. The test results show that the peak value of f is decreased by 15% due to the vibration effect.
