土压平衡盾构法隧道施工渣土改良指标探讨

摘要

简述了土压平衡盾构法的施工原理，根据设计及施工规范对渣土改良的要求，阐述了渣土改良的原则、目的、意义与相关指标，并通过渣土改良试验，得出了影响渣土性能指标的主要因素。%The paper indicates the construction principle for the soil pressure balance shield method,illustrates the principles,aims,meanings, and related indexes of the residue soil improvement according to the requirements of the design and construction regulation on residue soil im-provement,and concludes the main factors affecting the residue performance index by the residue soil improvement tests.
