Behavior of Stabilized Soils under Repeated Loading. Report 2. Behavior of Repeated Flexure, Frequency and Duration Effects, Fatigue Failure Analyses

摘要

The report presents results of experimental investigations of the comparative behavior of cement-treated silty clay and cement-treated buckshot clay under repeated compressive stresses, the behavior of cement-treated silty clay in repeated flexure, and effects of repeated load duration and frequency in both compression and flexure. Analyses are presented relative to the adequacy of stabilized layers to withstand flexural stresses imposed by specified design trucks and aircraft. Fatigue probabilities are examined and a method for assessing the probable effects on performance of variations in stabilized soil quality is described. (Author)
