摘　　要：本文通过试验观察了粘结锚固机理，从试验数据统计回归和应力状态分析建立了全过程τ－ｓ本构方程。应用计算机模拟试验探讨了锚固强度变化规律和临界锚长、极限锚长。通过可靠度分析建议了设计的锚固长度。In this paper,the bond-anchorage mechanism of deformed bars in concrete has been observed through experiments. By regression of the statistical of the experimental data and analysis of stress states,the -s constitutive equation for whole process is established.Hence, a simulation test by use of the computer is developed and theregularities of bond--anchorage strength, the critical and ultimate anchorage are researched through the results of computer analysis.Finally, using the reliability analysis, the design of anchorage length is p roposed.
