摘要
为了确定加宽方式对改建路基变形的影响,采用ANSYS软件建模和现场实测进行对比分析。对比分析模拟分析和现场监测结果,得出双侧加宽路基表面所产生的沉降变形较小,变形曲线较平缓,在施工条件允许的情况下应尽可能选择双侧加宽。
In order to determine the influence of the widening method on the deformation of the reconstructed subgrade,the ANSYS software modeling and field measurement were used for comparative analysis. Comparing and analyzing the simulation analysis and on-site monitoring results, it is concluded that the settlement deformation caused by the double-sided widening of the subgrade surface is small, and the deformation curve is relatively gentle.
