考虑古德曼接触的梯形渠道冻胀有限元模拟
Finite element simulation for frost heaving on trapezoidal canal consider Goodman contact
摘要
Abstract
In order to explore the mechanism of frost heaving damage for canal lining ,using the finite element soft-ware 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 re-sults 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 .关键词
