研究结果表明，盾构掘进对地下结构周围土体扰动有限，不会产生隧道整体漂移。
It was shown that the shield driving exerted a limited effect on the underground structures, the "excursion" of existing tunnel did not occur.
为保证开挖面稳定及控制地面沉降，土压平衡盾构掘进时必须合理匹配各施工参数。
For EPB(Earth Pressure Balance)shield tunneling, one must properly choose driving parameters to maintain face stability and control ground subsidence.
研究泥水平衡盾构掘进各阶段对土体的扰动机制、扰动规律、影响范围以及影响程度。
Then, the underlying laws, influential range, and influence degree for soil disturbance exerted by different stages of slurry shield tunnelling are analyzed.
