ABSTRACT: The assessment of support systems such as rockbolts and rock anchors are very important for the
maintenance of existing rock-engineering structures. The utilization of non-destructive tests is preferable to
destructive tests such as pullout tests. The dynamic responses of rock anchors and rockbolts could be used for
non-destructive tests. These tests should generally provide some information on the constructional conditions,
corrosion and axial force conditions. In the first part of this study, some theoretical models are developed for the
axial and trasverse dynamic tests and then results of numerical simulations are presented by considering
possible conditions in-situ. These conditions are the bonding quality, the existence of corroded parts or couplers
and pre-stress. The results of the numerical simulations could be very valuable for interpretation of the wave
responses to be measured in non-destructive dynamic tests in-situ.
