Analysis of Grout-Soil Shear Stress of Load Distributive Compression Anchor

Ground anchors are commonly used in construction to ensure safe support of various structures. Load distributive compression anchors (LDCAs) have recently been introduced as an improvement over conventional ground anchors and have been extensively used in the field. Understanding the load transfer mechanism of LDCA accurately is crucial to ensure structural stability. In this study, scaled-down model experiments with multiple anchor bodies were performed to analyze the load transfer mechanism of LDCAs. Experimental results showed that the bearing capacity of LDCAs decreases due to the interference effect between the anchor bodies. To investigate the interference effect, the load-displacement relationship of the anchor body and grout-soil shear stress distribution was evaluated.
