Analysis of Reinforcement Effect of Gravel Pile Combined Geotextile Reinforcement for Widening Highway Subgrade
In order to study the reinforcement effect of gravel pile geofabric reinforcement on expressway subgrade widening, the subgrade settlement before and after the subgrade widening was numerically simulated against the background of the general subgrade widening project from Anyang to Luoshan Expressway. The results show that the maximum settlement of the subgrade occurs at the new subgrade section centroid, the subgrade settlement is large in the middle and small on both sides, in a “bowl” shape; The post‐construction settlement without reinforcement measures is 6.3cm, and the post‐construction settlement with gravel pile geotextile reinforcement is 1.2cm, and the settlement is reduced by about 5cm. The reinforcement effect is remarkable and has certain feasibility, which provides experience for similar projects.
