将路基变形简化为二维问题,选取填方路基常见的三种断面形式,应用大型通用有限元软件Ansys,对路基变形进行弹塑性分析。研究了不同填土参数下,路基的变形问题,对于指导填方路基设计、施工,降低公路工程造价具有重要意义。
The deformation of subgrade is reduced to two-dimensional problem. The three common cross-sectional forms of subgrade are selected. The large-scale general finite element software Ansys is used to analyze the subgrade deformation. Studying the deformation of subgrade under different filling parameters is of great significance for guiding the design and construction of filled embankment and reducing the cost of highway engineering.
