摘要
新奥法在公路隧道施工项目中的应用尤其广泛,该技术很好地将隧道开挖与支护施工结合在一起,极大地提高了施工的标准化程度和可靠性。本文以新奥法开挖及支护施工技术为研究对象,分析了新奥法的施工原理及应用范围,进一步明确了新奥法常见开挖方式及支护结构的技术特点、施工工艺及应用条件。
NATM is widely used in highway tunnel construction projects,which combines tunnel excavation and support construction,greatly improving the standardization and reliability of construction.This paper takes NATM excavation and support construction technology as the research object,analyzes the construction principle and application scope of NATM,and further clarifies the common excavation of NATM Methods and technical characteristics of support structure,construction technology and application conditions.
