Centrifuge model test on the face stability of shallow

2011-6-22 · With the model sand used in the centrifuge tests, a D/d 50 ratio of about 125 was reached. Therefore, some caution is needed to appreciate the test results. Furthermore, grain size effects have been detected on the development of shear band patterns in a trap door test simulating chimney collapse [22, 24, 34].
