摘要

The vibration acceleration in fresh concrete relates to the consolidating and formingrnquality of pavement, and to the design, selection and use of vibrator parameters, as well as to therndisposition of vibrators. The aims of the paper are both how vibrator acceleration propagates inrnfresh concrete and how acceleration in fresh concrete is calculated when slipform paving. Thernlateral and longitudinal propagation of acceleration near sideforms and between two vibratorsrncaused by internal vibrator in slip forming concrete is tested and analyzed theoretically as wellrnas simulated by computer. Also, the calculating empirical formulas for acceleration in slipformrnpaving concrete are given in this paper.
