Abstract: Building foundation elastic pad is one of the important measures for subway vibration control.In order to understand the subway vibration control effect of elastic pad on superstructure, two identical concrete test blocks were poured on site near a subway line.Taking the real subway vibration load as the input source strength, the vibration isolation effect of elastic pad on upper concrete mass block was compared and analyzed; At the same time, the influence of the backfill around the underground foundation of the building on the vibration isolation effect is simulated and analyzed.The backfill has a non negligible restraint effect on the building, improves the vertical natural frequency of the "building -elastic pad" system, and then reduces the vibration isolation effect of the elastic pad.Therefore, the influence of surrounding soil on vibration isolation effect should be fully considered in the application design of building foundation elastic pad engineering.
