This study aims to make clear pipe jacking mechanism, taking account of the whole pipe line and the interaction between ground and pipe surface, and propose a method to evaluate acting load on pipe surface and required thrust force, to realize long distance jacking at sharp curve safely and economically. A prototype test on joints, site measurement, and parametric study were carried out to validate the developed model. As a result, it was confirmed that the developed model can simulate pipe line behavior reasonably well.
