对杜家山千枚岩公路隧道施工经验的深思

摘要

Based on the construction experience of Guanggan Expressway phyllite tunnel, it is believed that geological exploration data should be made full use of in the process of design and construction and the "new Austrian tunneling method" is not the only method for tunnel construction. Appropriate construction methods should be taken according to the characteristics of surrounding rock.%结合广甘高速千枚岩隧道的施工经验，认为在设计与施工过程中要充分利用地勘资料；认为“新奥法”并不是隧道唯一的施工方法，要根据围岩的特性分别采用相适应的施工方法。
