9、manceanalysisofanchorrodcomponents锚杆构件作为岩土工程中的重要支撑和固定元件，其力学性能直接决定了工程的安全性和稳定性。锚杆构件的力学性能主要包括抗拉强度、抗剪强度、抗弯强度以及延展性等。这些性能不仅与锚杆的材料性质有关，还与其结构设计和制造工艺密切相关。Asanimportantsupportingandfixingelementingeotechnicalengineering,themechanicalpropertiesofanchorrodcomponentsdirectlydeterminethesafetyandstabilityofthepro

11、，其抗拉强度必须足够高，以承受可能出现的最大拉力。抗拉强度的大小主要取决于锚杆的材料选择，如钢筋、钢绞线等高强度材料的应用，可以有效提高锚杆的抗拉强度。Tensilestrengthisoneofthemostfundamentalmechanicalpropertiesofanchorrodcomponents.Duringtheworkingprocess,anchorrodsmainlybearthetensileforcefromtherockandsoil,therefore,theirtensilestrengthmustbehighenoughtowithstandthemaxi
