This paper describes the results of full-scale model tests and numerical analyses of placing fresh concrete in bored piles to investigate the flow process of high-strength concrete after pouring ordinary concrete by tremie method. The vertical cross section through the cured test pile shows that the high-strength concrete spreads over the previously placed ordinary concrete. The flow patterns obtained by the numerical analyses based on computational fluid dynamics are good agreements with the test results. The analysis method has possibilities to simulate flow behavior in bored piles.
