| Abstract | Soil nails are used to prevent landslides in man-made or natural embankments. The need to install a large number of soil nails in regions of the world where site inspections are infrequent makes quality assurance difficult to achieve. The objective of this study was to develop a non-destructive field procedure using the impulse-response (IR) technique, which could quickly determine the length of installed nails. The study comprised two parts; experimental testing of laboratory and in-ground nails and the development of finite element models for the nails based on the tests. The study showed that the length of short simple nails (steel bar only) could readily be determined using the IR technique. The study also showed that the mechanical properties and condition of the cementitious cover in composite nails dominated the dynamic response and behaviour of the nails. Knowing the longitudinal wave velocity of the cementitious cover was the key parameter for obtaining a reasonable estimate of nail length. |
