Tóm tắt:

This paper presents the results about the effect of frequency and effective consolidation stress on potential liquefaction of alluvial sand, within the lower part of Thai Binh Formation (aQ23tb1) in the Hanoi area by using cyclic triaxial experiment, which is an effective method to study the potential of liquefaction. The results indicated great influence of frequency and effective consolidation stress on the liquefaction potential. The higher the frequency is the greater the liquefaction becomes. On the contrary, the liquefaction potential decreases when the effective consolidation stress increases. When the effective consolidation stress is higher than 140kPa, frequency is 2Hz, the magnitude of shear stress is 50kPa, and the sample is practically nonliquefiable.
