摘　　要：盾构隧道掘进过程中,开挖面的支护压力是一个极为关键的控制参数。本文结合广州的软弱地层及地下水丰富的情况,采用孔隙水和土骨架的完全耦合理论,分析提出了砂土地层中盾构隧道支护压力的适当范围。In shield tunneling process, the excavation face support pressure is a very important control parameters for the tunnel quality. Considered the Guangzhou soft stratum as well as the abundant ground water situation, This paper derived the the appropriate scope of support pressure for the Shield tunnel excavation face in Sand stratum by using the finite element model based on the fully coupled theory of pore water and soil skeleton.
