Research on reinforced anchor with fibre mortar

With the development of highway construction, more and more slopes need to be tackled with better anchors. Reliable anchorage effect is one of the important factors for a stable slope. Grouting material plays an important role in providing more powerful, more stable and more endurable anchorage capability. Many laboratory and in situ tests have been performed with a new type of mortar mixing with the fibers. It has been found that the application of the fiber mortar improves the cohesive strength between the mortar and the surrounding rocks and the crack resistant strength of the anchorages. Furthermore, an elasto-plastic finite element program has been applied to simulating the process of anchorages action. Analyzing results show that the fibre mortar can prevent the anchorage from cracking and improve bearing capacity.
