摘要
以青藏铁路路桥过渡段作为ANSYS分析模型,采用一种8节点高级单元进行模拟,得出热棒对路桥过渡段的降温效果以及沉降差影响.有限元分析结论对多年冻土区路桥过渡段不均匀沉降采用热棒路基来治理是否合理提供了理论依据.
In this paper,the transition section of Qinghai-Tibet railway bridge is taken as ANSYS analysis model with an 8-node advanced simulation unit. Finite element analysis concludes that the hot stick has effect on cooling performance and the differential settlement of the bridge transition section,which provides a theory basis for the construction of uneven settlement of bridge transition section in permafrost regions.
