根据寒区渠床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 板沿斜坡整体上移是板正常的变位，板的隆起架空现象就是板的失稳破坏。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
According to the theory of uneven frost heave caused by the uneven distribution of moisture content along the cross-section height of the drainage bed, the frost heave and displacement of the slope plate is analyzed, and the mutual restraint relationship between the plate and the frozen soil is studied. Slope plate in the actual project along the slope as a whole move uplift and the phenomenon of overhead plate along the slope of the overall shift is the normal plate displacement, the plate is the uplift of overhead phenomenon of plate instability damage. It is clear that the stress model of channel retaining panel when it is frost heaved is determined that the side slope is a biasing component and the bottom plate is the compression and bending component. Therefore, a more complete internal force Calculation method
