| 中文摘要: |
| 为对比分析不同材料U形渠道对其抗冻胀效果的影响，采用有限元分析软件ADINA以衬砌板为研究对象进行仿真模拟分析。结果表明，玻璃钢渠道阴、阳坡最大冻胀变形比混凝土大27.44%、27.34%，但冻胀变形变化率减小了4.49%~16.19%，冻胀变形均匀；玻璃钢渠道有很强的适应变形能力，使衬砌板的等效应力、法向冻胀力分别减小了43.86%、39.96%，很大程度上减小了渠道的冻胀破坏，值得实践并推广。 |

| In order to study the response of U-shaped channel of different materials to frost heave, the paper carried out numerical simulation by using ADINA software with channel lining board as research object. The results indicated that the displacements of GFRP are more 27.44%、27.34% than that of concrete in both sides of channel respectively,but the change rates of displacement decrease by 4.49% to 16.19%, the variation of frost heave is uniform; GFRP has more strong ability to adapt to deformation.The equivalent stress and frost heave force of channel lining are decreased by 43.86% and 9.96%.The U-shaped channel of GFRP can reduce the frost heaving break of channel to a large extent and is worth being widely practiced and popularized. |
