- Abstract
The vibrating and screening is easy to break the particles of brittle geomaterials, which is difficult to obtain real gradation and also brings difficulties to engineering guidance. In order to find out the reliability of the vibrating and sieving method for testing the gradation of fragile geomaterials, the vibrating and sieving test of different time was carried out with coral sands. The results show that the vibrating and sieving time has a great influence on the gradation of coral sands. And the quality of the each particle group coral sands changed considerably in the first 25 min, and the changes slow down after 25 min of vibrating and sieving. Except for coral sands with particle diameters of 10 ~ 20 mm and 1 0.25 ~ 0.5 mm, coral sands with other particle diameters shared a significant change in the vibrating and sieving test. The characteristic particle diameters of coral sands also change most greatly in the first 25 min of of vibrating and sieving. The non-uniformity coefficient Cu and curvature coefficient Cc are changed the most in the first 10 min of vibrating and sieving, and then the non-uniformity coefficient Cu continues to increase, but the curvature coefficient Cc is basically unchanged. Vibrating and sieving continually change the particle size of coral sands, which will cause its gradation to constantly recombine and its properties to constantly change. The reliability of the test results decreases with the vibrating and sieving time.
