In pipe jacking method, the main factor influencing on jack force is the friction resistance between pipes and ground, and the over-cutting area between pipes and ground is a significant factor giving influence to the friction resistance. Therefore, the excavation radius by TBM is a little bit larger than the outer radius of pipes to reduce the friction resistance. So far, most of the models estimating jack force do not consider the over-cutting area, and the pipe behavior is not still clarified well. To overcome the above problems, the new analysis model called as “stack pipe model” has been developed, which can take over-cutting into consideration. This study aims to validate this analysis model by site measurement data. As a result, it was confirmed that the developed stack pipe model could represents the measured pipe behavior during pipe jacking reasonably.
