Interactive design - Croatian experience

The Croatian experience with the application of the interactive geotechnical design is presented. The interactive design includes extensive in situ monitoring during construction, which was performed on several deep excavations supported by rock bolts, particularly in urban areas, and also in installed piles during the construction of a highway viaduct. According to the interactive design, contingency measures are taken when the stability of the structure is endangered, and the original design is changed, if necessary, for the subsequent construction stages. The in situ measurements provide a valuable data base for the study of the soil and rock behaviour in general. The procedure of grouted rock bolt pull-out testing with the simultaneous use of acoustic emission is also presented. This procedure is a very valuable addition to the interactive design and it can be recommended for in situ quality control of rock bolts.
