A CASE STUDY ON AN EFFECTIVE REDUCTION IN STRUCTURE-BORNE SOUND USING UNDERGROUND VIBRATION-ISOLATION WALL AT A CULTURAL COMPLEX FACILITY ADJACENT TO A RAILROAD (PART 2)

Abstract

We developed a vibration-isolation separator unit for sheathing boards. As a result of the hydraulic and tension test, it was confirmed that this separator unit has an enough cut-off performance against the leak of cement paste, and has enough rigidity and yield strength. We examined that this separator unit shows almost the same vibration-isolation performance as the non-separator method.
