The finite difference element software FLAC 3D was used to simulate the reconstruction and expansion project of Xinle-Yuanshi expressway. The model of reinforced soil slope widening subgrade was established. Based on the comparison of the simulation data of the sections with different heights and structural forms, the structural behavior of reinforced soil structure in subgrade widening project was analyzed. The law of structural deformation and construction control technology were summarized.

... The characteristics and progression of settlement because of road widening construction activities have been examined through small-and large-scale model tests [9,30], centrifuge tests [11,31], numerical modeling [12,14,17,27,[32][33][34][35][36][37], and field tests [20]. As differential settlement develops in the middle of the embankment, transverse cracks simultaneously appear at the surface [38]. ...
