Estimations of the Jacking Forces of Large-Sized Rectangular Jacking Pipes Based on a Displacement Control Method

Table 1

Different models and their advantages and disadvantages.

ModelMerit and demerit

Estimation model of jacking force based on rigid body balance [811]; O’Reilly et al. [1218]The rigid body assumption of pipe jacking is different from the actual working condition
Jacking force estimation model based on deformed body [6]Partial contact and failure to consider the influence of grouting pressure on pipe jacking state
Finite element method model for displacement control (proposed in this study)Overcome the above shortcomings, more in line with engineering practice
