| 中文摘要: |
| 为了探究渠道衬砌冻胀破坏的机理，利用有限元软件ABAQUS对梯形渠道的冻胀过程进行了先热后力的数值模拟。在模拟过程中分为考虑古德曼接触的模型和不考虑接触的模型，将得出的结果分别与原型渠道的数据相对比，结果表明，考虑古德曼接触的模型更符合实际情况，能够很好地解释渠道冻胀破坏的位置常在渠道底板中间以及距离坡脚1/3坡板处的现象，其所得结果可以应用于渠道的抗冻胀设计。 |

| In order to explore the mechanism of frost heaving damage for canal lining, using the finite element software ABAQUS, carried out the numerical simulation through first thermal and after force for the process of frost heaving on trapezoidal canal. In the simulation process can be divided into two conditions as considering Goodman contact model and non-consider contact model. The obtained results were compared with the prototype canal data, respectively. The results showed that: The considering Goodman contact model was more conformed to the actual situation and can be well explained the phenomenon as the frost heaving damage position was at the middle of the canal bottom plate and 1/3 of the slope plate distance foot of 1/3 slope plate. The obtained results can be used in design for anti-frost in canals. |
