摘要: Regarding the freezing damage of high-grade highway subgrade in seasonally frozen area, the thesis explores the effect on the dynamic behavior of subgrade soil under freeze-thaw cycles and draws the change law of parameters (including dynamic strength, dynamic cohesion, and internal friction angle; and dynamic elastic modulus) of high-grade highway-subgrade soil with the number of freeze-thaw cycles. It aims to provide the reference for operation and maintenance of a high-grade highway. Conclusions: (1) Dynamic strength tends to decline evidently after freeze-thaw cycles, with 60%~70% decline after three cycles, and remains stable after five to seven cycles. (2) With the number of freeze-thaw cycles increasing, the internal friction angle fluctuates within a certain range without an obvious change law, only presenting the tendency of dropping off. The dynamic cohesion declines obviously, about 20%~40% after seven freeze-thaw cycles, and then tends to be stable. (3) With the number of freeze-thaw cycles increasing, the dynamic elastic modulus and maximum dynamic elastic modulus are inclined to decrease distinctly. After five freeze-thaw cycles, the former declines 30%~40% and then remains stable. Meanwhile, the latter falls 20%~40%.
