چکیده انگلیسی
Dynamic triaxial experiments were conducted to investigate the cumulative plastic strain behavior of frozen aeolian soil. Under highway dynamic loading, the effects of several factors including frozen temperature, dynamic amplitude and loading frequency, water content and confining pressure on the cumulative plastic strain of frozen aeolian soil were studied. The results show that the cumulative plastic strain of frozen aeolian soil increases as the temperature and water content rise and as the confining pressure decreases, while the cumulative plastic strain increases slightly as the loading frequency decreases. Besides, with the increase of the dynamic amplitude, especially when the dynamic amplitude is greater than 0.08 MPa, the effects of water content and confining pressure on the cumulative plastic strain become more significant. Finally, the function of the cumulative plastic strain of frozen aeolian soil was obtained through back-fitting a series of testing results.
