摘要
总结了开挖面稳定性的各种分析方法,对高水压小覆土泥水盾构开挖面稳定机理进行了研究,分析了泥水平衡机理,提出了泥水压力设定的方法和适用条件,分析结果为完善盾构隧道开挖面稳定理论及指导现场实践提供了有益的方向。
This paper summarizes the analytical method for the stability of excavation face,studies the stability mechanism of high water pressure slurry shield excavation face,analyzes the slurry balance mechanism,and proposes the slurry pressure determination method and application conditions.Analytical results have provided beneficial direction for improving shield tunnel excavation face stability theory and guiding in-situ practice.
