岩土控制变形工法具有经济和施工进度的可控性,在欧洲隧道建设中被广泛采用。本文依托宁波野猪山隧道工程,介绍了公路隧道采用岩土控制变形工法施工的探索尝试,从设计施工技术、施工效果现场监测、经济性等三方面分析,分析结果显示在类似该软弱围岩地质条件下,采用岩土控制变形工法施工具有较好的适用性、安全性和经济性。随着国内施工人工费高涨和施工安全的日益重视,以机械化施工和大断面开挖为特色的新意法施工方法,在施工造价和施工进度的控制方面具有极大的优势和竞争力。
Geotechnical Control Deformation method with economic and construction controllability, is widely used in the construction of the European tunnel. This paper, based on the project of the wild boar tunnel in Ningbo, introduces the exploration attempt of the construction of highway tunnel using geotechnical control deformation method. The analysis includes three aspects: design and construction technology, site monitoring of construction effect and economy. The results show that, Conditions, the use of geotechnical control deformation construction method has good applicability, safety and economy. With the increasing construction labor costs and the increasing emphasis on construction safety, the new method of construction, which features mechanized construction and large-section excavation, has great advantages and competitiveness in construction cost control and construction schedule control.
