Steel plates with mass of 1500 g each were stacked on topof a 75 mm diameter and 150 mm high clay specimen,as shown in Figure P2.22 (attached). If the undrained shear strengthof the specimen is 45.0 kN/m2, how many plates can bestacked before the specimen fails? What is the consistencyterm for this clay?
1.In an oedometer test a specimen of saturated clay 19 mm thick reaches 50%consolidation in 20 min. How long would it take a layer of this clay 5 m thick toreach the same degree of consolidation under the same stress and drainageconditions? How long would it take the layer to reach 30% consolidation?
A specimen of normally consolidated clay was consolidated under a chamber confining pressure of 280kpa for a drained test by how much does the axial stress have to be reduced to cause failure by axial extension?
