随着我国经济的发展与现代工程结构的发展，预埋钢筋在隧道工程，砌体结构、玻璃幕墙中得到了广泛应用。预埋钢筋与周围介质粘结性能的好坏直接影响到工程质量。因此，进一步深入研究锚固系统界面之间的粘结性能显的尤其重要。 运用理论分析与室内试验相结合的手段，对预埋钢筋与周围介质之间的粘结锚固机理进行了系统的研究，对其破坏机理进行了较为全面的分析，并取得一些有意义的成果： 1、从理论上建立预埋钢筋破坏的双曲线模型，确定出粘结力 与轴力p的计算值，结合试验数据验证模型的正确性。 2、根据试验测得的荷载—位移曲线，总结出预埋钢筋的拉拔破坏过程在宏观上可划分为微滑移段、内裂滑移段、劈裂段、下降段和残余段五个阶段，并应用声发射检测技术，指出粘结滑移的声发射能量特征与载荷滑移呈同步变化关系，从而验证了预埋钢筋拉拔破坏时的的五个破坏阶段。 3、根据粘结强度的理论计算公式，指出影响粘结强度的因素为：锚固长度、锚固直径、周围介质强度。结合试验数据，运用最小二乘法进行曲线拟合，分别得出粘结强度与各影响因素之间的具体关系式。 4、从理论上推导出发生锥形破坏时的最小锚固长度公式，通过实测数据进行验证，得出可通过钢筋直径、钢筋强度、钢筋截面积及混凝土抗拉强度四个参数可计算出实际中产生锥形破坏的最小锚固长度。 5、使用Mohr-Coulomb准则，根据钢筋拔出的实际破坏面，推导出极限状态下的测强公式，将理论计算值与试验中周围介质抗压强度的实测值进行对比，得出在适用的强度范围内可以通过实际拉拔力来确定周围介质的强度。

In recent years, as economic development and the development of structure engineering，Embedded reinforcement has been widely used in the tunnel engineering, masonry structure and glass curtain wall. The affect factors of the bonding properties is very complex and it affects project quality, so, it is important to make a further study of bonding between embedded steel bars and surrounding medium. Paper based on theoretical analysis and laboratory test, make a systematic study of the mechanism between reinforced and ambient medium. Make an all-round analysis about its breach of the mechanism. Made some significant achievements: 1. Establish a embedded steel hyperbola destruction model in theoretically. Determined cohesive force and shaft force’s calculated value. Verify the validity of data model with the experiment. 2. Based on the test of loading curve-displacement. Summary of the embedded reinforced of drawing process can be divided into the five stages: slide smooth passage, snowflake smooth passage, cleavage passage, decline passage and remains passage, and then point out bonding slip of the characteristics of sound energy and loads moving synchronize changes in relationship with the emission testing technology. Further verify that the advance in drawing the reinforcement of the five destruction stages. 3. According to the intensity of adhesion to the formula, point out influence the cohesive strength factors are anchorage length, anchorage diameter, surrounding medium strength. With the experiment data, use the least square method to curve fitting. Get the relationship between the cohesive strength and influence factors. 4. In theory, we get the fixing length of the formula when Damage occurred in the heaving and mapping data validation. Arrive at use the bar diameter, characteristic value of strength of steel bar, sectional area of bar, tensile strength of concrete. When actual destruction happened, we can calculate the fixing length with four parameters. 5. According to the actual destruction surface and using Mohr-Coulomb guidelines, derive the test strong formula of maximum condition. Compare the theoretical calculation the pressure on the strength of the surrounding medium in experiment. Arrive at in the applicable range can use actually pulls force to determine the strength of the surrounding medium.
