Bearing plates are structural steel components engineered to distribute concentrated loads across larger surface areas in deep foundation systems, particularly in tieback and ground anchoring applications. These critical load-transfer elements function as the interface between anchor heads, tensioning equipment, or prestressed tieback systems and the underlying soil or rock formations. Typically fabricated from high-strength structural steel with yield strengths ranging from 250 MPa to 355 MPa, bearing plates are specifically designed to prevent localized soil failure, differential settlement, and surface breakout phenomena. Their composition comprises steel alloys conforming to European or international standards, frequently incorporating protective surface treatments such as hot-dip galvanizing or epoxy coating systems to ensure durability in corrosive subsurface environments and extended service life in demanding geotechnical conditions. In deep foundation engineering, bearing plates provide essential load distribution functions across multiple specialized applications. They serve as primary bearing surfaces in prestressed tieback systems, anchoring wall systems, and ground stabilization projects, where anchor tendons or struts transfer concentrated tensioning loads into surrounding soil strata or rock masses. Bearing plates are integral to micropile and small-diameter pile installations, preventing punching shear failures at critical soil-structure interfaces. They are routinely specified in permanent and temporary ground anchor systems for deep excavations, retaining wall support, slope stabilization, dam construction, and geotechnical reinforcement projects. In all applications, bearing plates ensure adequate load distribution while preventing local failure mechanisms and guaranteeing efficient transfer of anchor forces into competent bearing strata. Bearing plates are supplied as prefabricated steel components in standard rectangular or circular geometries, arriving at construction sites with protective coatings intact. On-site storage requires dry conditions to preserve coating integrity prior to installation. During installation, the bearing plate is positioned against the anchor head or reaction frame assembly and firmly secured against the soil surface to ensure full contact across the bearing interface. The installation methodology varies by tieback system type, encompassing threaded connections, welded assemblies, or bolted configurations. Surface preparation typically involves removing loose soil and debris from the bearing surface to establish consistent, uniform load transfer characteristics. Standard bearing plate variants range from basic flat plates through conical designs for angled loading applications to reinforced configurations for extreme-load scenarios. Thickness specifications typically span 10–40 mm, with lateral dimensions from 150×150 mm to 400×400 mm or larger, depending on load requirements and site conditions. Common structural grades include S275 and S355 steel, selected based on anticipated tensioning loads and safety factor requirements. Engineering selection of bearing plates requires calculating the minimum bearing area based on maximum anchor loads, allowable bearing stresses within specific soil types, and project-specific safety factors. Subsurface conditions, anchor orientation, and design life all influence plate dimensions and material grade specifications. Bearing plates must comply with EN 10025 (structural steel standards), ASTM A36 or A572 (American specifications), and geotechnical design codes including EN 1997-1 (Eurocode 7). Marine or chemically aggressive environments require compliance with EN ISO 1461 hot-dip galvanizing standards or equivalent protective specifications.
