青藏铁路多年冻土区无缝线路变形分析
Continuous welded rail in permafrost regions deformation analysis of Qinghai-Tibet Railway
摘要
Abstract
The paper study about under the condition of vertical settlement of track deformation analysis. Analysis of track displacement distribution and the law of development under the condition of embankment settlement diseases based on nonlinear finite element method. Research indicates that rail vertical displacement and roadbed subsidence has the linear relationship in the range of track bed resistance to be effective. When the roadbed arch and sink alternately that will be a significant increase in rail displacement.关键词
