| Abstract: | Based on the feasibility study, a series of experiments have been conducted in situ on the anchor established by fracture grouting. The results show that the fracture grouting not only increased the volume and the surface area of a fixed anchor length,but also strengthened the mechanical characteristics of the soil around the anchor. Therefore fracture grouting greatly increased the bearing capacity of anchor. |
