摘 要: | 基于某高速铁路试验段路基沉降的实测,建立有限元模型进行模拟,得出了和实测拟合较好的计算结果。实测及有限元分析表明:路基填筑完成后预压三个月,沉降仍有一定发展趋势,不足以消除后期沉降的影响,路基在填筑后沉降发展需要很长时间才能完成。

Abstract: | Subgrade settlement was simulated with a finite element model established on the basis of the data measured in the testing section of a high-speed railway, then a result fitted the measured result was obtained. The result of the actual measurement and the FEM analysis thereof show that through 3-months preloading after the subgrade filling, the settlement still develops and the effect of the post-construction settlement is not eliminated completely; hence, it takes a long time to finish the development of subgrade settlement after construction. |
