摘要
结合二维有限元模型,对路基路面的纵向不均匀变形的波幅及横向不均匀变形引起的路面结构附加应力进行数值模拟分析,并为青藏公路路基路面不均匀变形的处治措施提供理论依据。
According to characteristics and influential factors of uneven deformation of Qinghai-Tibet highway roadbed, the essay establishes fi- nite element model, carries out numerical analysis on the auxiliary stress of road structure owning to uneven deformation and deformation of road- bed. The analytical conclusion has provided theoretical basis for dealing with uneven deformation of Qinghai-Tibet highway roadbed.
