结合相关规范，利用通用有限元软件 ADINA对季节性冻土区不设置保温层与铺设保温苯板下的渠道温度场进行了数值模拟对比分析。结果表面：铺设保温苯板后的渠道，不仅苯板下温度已为正温，而且冻胀量相对于未设置苯板的渠道明显减小，充分说明保温法对于渠道抗冻胀是一种有效的措施。
結閤相關規範，利用通用有限元軟件 ADINA對季節性凍土區不設置保溫層與鋪設保溫苯闆下的渠道溫度場進行瞭數值模擬對比分析。結果錶麵：鋪設保溫苯闆後的渠道，不僅苯闆下溫度已為正溫，而且凍脹量相對于未設置苯闆的渠道明顯減小，充分說明保溫法對于渠道抗凍脹是一種有效的措施。

By combining the relevant specification ,this paper used the universal finite element software ADINA to do numerical simulation analysis about channel temperature field in seasonal frozen regions without insulating layer and with insulation ben-zene board .The result shows that not only the benzene board temperature is positive ,but also its frost heave is obviously re-duced ,this fully shows that the heat preservation method is an effective measure .
