Cyclic Stress-Strain Characteristics of Clay

摘要: The decreases in moduli and increases yield strain occurring during cyclic loading of sensitive clay under simple shear conditions are examined. representative those associated with the upward propagation a seismic wave through large mass soil; i.e., is completely reversed each cycle at rate 1 cps. reported defining bilinear hysteresis models which best fit nonlinear stress-strain characteristics obtained from tests. For San Francisco Bay Mud constant for levels greater than 2% cycles after fiftieth. Yield strain, however, proportional to level least 200 cycles. strength measured static decreased by involving strains, but only modulus restricted strains below about 1%.
