摘　　要：文中利用ANSYS软件,针对农田水利中常用的5种不同断面形式的渠道进行有限元数值模拟,比较在过水流量相同的情况下各渠道的冻胀情况。模拟结果表明,断面形式为弧底坡脚梯形的渠道抗冻胀性能最好,为今后在渠道防冻胀设计提供了一定的参考和依据。In this paper,using ANSYS software,the finite element numerical simulation is carried out for five kinds of channels with different section forms commonly used in irrigation and water conservancy,and the frost heaving situation of each channel is compared under the same flow rate.The simulation results show that the channel with arc arc bottom slope foot trapezoid has the best anti-frost heave performance,which provides a certain reference and basis for the anti-frost heave design of the channel in the future.
