Study on Application in Post-Earthquake Roads' Repairing of Crushed-Stone Grouting Pile

In post-earthquake road rapid repair and reinforcement engineering, the key problem is to accelerate the consolidation of soft-soil roadbeds in the shortest time. Crushed-stone grouting pile construction is simple and reinforces the soil with gravel and grouting to form a stable embankment structure, which can reduce subgrade settlement. According to the special requirements of road rapid repair and reinforcement engineering, crushed-stone grouting pile technology is proposed. A crushed-stone grouting pile roadbed numerical model is established, and analysis shows that this kind of pile can reduced the settlement of subgrade deformation and increase the stability of reinforced slope roads.
