摘要	Soil has a certain memory for stress history, whose mechanical property is also related to time effect. To consider the influence of stress history and consolidation time on shear modulus of expansive soils, resonant column tests were carried out with compression stress paths of loading and unloading by different consolidation time. Results show that both stress history and consolidation time have a pronounced influence on the shear modulus and its decay rule. The time effect of loading path on shear modulus of expansive soils is different from that of unloading path. Under the loading path, the shear modulus of the soil enhances with consolidation time increasing, which has a positive linear correlation with the logarithm of consolidation time. While under the unloading path, the shear modulus decreases first and then increases with the increase of consolidation time, which is related to the logarithm of consolidation time as a quadratic function. Furthermore, the shear modulus-consolidation pressure curves of expansive soils also show different rules in loading path and unloading path. Under the loading path, the shear modulus shows a positive linear correlation with the consolidation pressure, while under the unloading path, the shear modulus shows a positive linear correlation with the logarithm of consolidation pressure. Conclusion can be drawn that the influence of stress history and time effect on shear modulus should be taken into account in engineering design and construction.
