| 摘 要： | 根据寒区渠床土沿断面高度含水率分布不均致使冻土产生不均匀冻胀量的理论，分析边坡板的冻胀变位，研究了板与冻土间的相互约束关系，合理地解释了边坡板在实际工程中沿斜坡整体上移和隆起架空的现象。明确了渠道护面板受冻胀时的受力模型，确定边坡板是偏压构件，底板是压弯构件，从而提出了较为完整的寒区刚性护面渠道护砌层受冻胀时的内力计算方法。

| Abstract: | The paper investigates the mechanisms,which cause (1) the upmoving of side lining slates of a canal and (2) the destruction of the slates due to bulging and building on stilts,and develops a stress model of frozen lining slates.Based on the model,it is concluded that the side lining slates are eccentric compressing members and the bed slate is a compressing and bending member.Two sets of formulas are presented to calculate the stress of frozen side and bed slates. |

| Keywords: | rigid lining canal side lining slates force of frost heave the frozen strength of soil |
