| Zusammenfassung |
| Shearing tests with a thin layer of clay between filter slabs render possible
large and cyclic deformations with drainage. In the pressure range of 100 kPa
they serve to validated visco-hypoplastic constitutive relations. This theory
is also confirmed by tests with up to 14 MPa and super-imposed anti-plane
cycles. After this kind of seismic disturbance the clay stabilizes if the
ratio of permanent stresses is undercritical. Otherwise a spontaneous
acceleration occurs after a delay. This could help to understand critical
phenomena with clay smears in faults. |
