Abstract
Fifteen constant rate of strain consolidation tests were performed on Wenzhou clay specimens under various strain rates and initial water contents using an advanced oedometer to investigate the remolded yield stress during compression. The results for different initial water contents indicated that the remolded clay compression curves could be expressed by a unique trend line using the void index. The porosity parameter was proposed based on existing strain rate parameters to qualitatively describe the relationship between porosity and remolded yield stress. It was observed that the greater the strain rate, the smaller the strain under the same vertical effective stress.
