DISCUSSION ON EVOLUTIONARY LAW，ATTENUATING CHARACTERISTIC AND CALCULATING METHOD FOR THE SHEARING STRESS OF THE SECOND INTERFACE OF ANCHORAGE TYPE STRUCTURES
Abstract：Research on the distribution，evolutionary law，attenuating characteristic and action mechanism of the shearing stress for the second interface of anchorage type structures is the basis and precondition for scientific and reasonable design of anchorage type structures. At present，all internal and external technical standards adopt the concept and method of average shearing stress for engineering design. This may cause disadvantage and potential risk. The internal and external research states are discussed since the 1960s for this problem. The results show that it is necessary to study this problem thoroughly.
