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

In the present study, based on previous research results, a finite element method that considered the grouting pressure and displacement control of the tube-soil side friction coefficients was established for the purpose of estimating the jacking forces of large sections of rectangular pipe jacking....
