摘要：

根据实验研究要求，在分析现有盾构实验台设计的基础上，提出密封舱压力场模拟实验台的设计方案，以验证通过数值方法获得的土压平衡盾构密封舱压力分布的准确性以及压力控制方法的有效性。实验结果表明，该实验台设计方案是可行的，该实验台可用于密封舱压力分布准确性以及压力控制方法有效性的实验验证研究中，能够为土压平衡盾构的设计、施工控制提供依据。

Abstract:

According to the requests of experimental study, on the basis of analysis on design method of existing experimental table, a design proposal for experimental table was presented,which was used to simulate pressure field of working chamber. The table was applied to verify accuracy of pressure distribution obtained from numerical simulation, and to verify validity of pressure control means of working chamber of earth pressure balanced shield. The experimental results show that experimental table is feasible and it can be used for experimental study mentioned above. This work gives a basis for design and control of earth pressure balance shield.
