A study was conducted to investigate the load transfer mechanism of ground anchors through a series of field experiments and numerical modeling. Optical FBG sensors, embedded into the center king cable of a 7-wire strand, were applied to the different ground conditions to monitor the distribution of tensile force along the tendons. The observed measurements of the in-situ load tests were compared with equivalent case studies simulated in the finite difference method, Flac 3D program. There is a good agreement between the experimental and numerical results. Both of them indicated that the tensile force remains constant at the free anchor length before dropping to zero at the distal end of the bonded anchor length. In addition, it is worth noting that the load transfer depth is different, short in hard rocks and longer in weak rocks depending on the ground conditions. This finding is particularly important when designing anchor and satisfying implicit economic criteria.
