采用极限分析理论的上限法计算了带压盾构前主动和被动极限压力。两个平移运动学允许的破坏机制被认为是计算方案。给出了数值结果，并与其他作者给出的结果进行了比较。
The upper-bound method of the limit analysis theory is used to calculate the active and passive limit pressure in front of a pressurized shield. Two translational kinematically admissible failure mechanisms are considered for the calculation schemes. The numerical results obtained are presented and compared to those given by other authors.
