设有扩大基础的台背回填基底应力有限元分析

The Finite Element Analysis of Basis Stress of the Backfilling Approach Embankment Equipped With Expanded Foundation

桥头台背回填的质量直接决定车辆行驶质量,文中结合实践从新的角度提出另外一种台背回填形式,并通过有限元分析提出了台背路基基础的设计原则。

The quality of backfilling embankment is critical to the quality of traveling. Combining with the practice, this article proposes an other kind of backfilling form from the new angle ,and proposes backfilling foundation principle of design through the finite element analysis.
