The invention relates to a method for manufacturing saturated surface-dry sand by utilizing the centrifugal-force principle. The method comprises the following steps: (1) putting completely-soaked wet sand on a centrifugal device, and throwing out redundant water in the sand under the centrifugal force more than n times of gravity acceleration; (2) absorbing the redundant water by utilizing the water absorbing material to prevent the water from returning into the sand, and finally obtaining the sand in a saturated surface-dry state. The saturated surface-dry sand with unified state can be manufactured by fixing parameters such as the weight of the wet sand, the overall dimension of the centrifugal device, the rotating speed of the centrifugal device, the rotating time of the centrifugal device and the water absorbing material and the like. According to the method, the test repeatability is good, the benefit for unifying data of different laboratories is achieved, and further the concrete control level is improved; in addition, the test method is fast and the labor intensity can be reduced.
