堤顶公路路面材料冻融破坏的数值模拟

Numerical modeling of pavement materials of levee crown highway destroyed by freeze-thaw

在3种混凝土路面材料冻融循环实验基础上,通过Ansys有限元软件分别对普通混凝土、碳纤维混凝土及沥青混凝土路面进行冻融损伤过程的数值模拟。探讨3种混凝土在冻融循环过程中的性能差别以及在季节性冻土区3种混凝土的实用性。

On the basis of 3 kinds of concrete pavement materials＇ freeze-thaw cycles, Ansys finite element software is used to simulate the process of freeze-thaw damage of ordinary concrete, carbon fiber concrete and asphalt concrete. Differences performance of 3 kinds of concrete in the process of freezing and thawing cycles is mainly discussed, which three kinds of concrete is practical in seasonal permafrost regions.
