For the electrical control system of push pipe driving machine, the adjustment of jacking force is critical to balancing the resistance force and moving the pipe string forward. This force should be well under control so as to avoid both the collapse (active failure) and the blow-out (passive failure) of the soil mass near the tunnel face. The aim of this paper is to determine the collapse and blow-out face jacking force of a rectangular tunnel. The analysis is carried out in the framework of the kinematic method of limit analysis theory. The numerical results obtained are presented and analyzed.
