摘要
通过青山隧道Ⅱ、Ⅲ类围岩上下台阶法施工及特殊地段处理等施工实践,认识新奥法设计与施工关系,并通过施工观察,洞内外的地质调查,岩土力学实验及现场监控量测等施工反馈信息,分析确定围岩的物理参数,及时确定和调整支护参数。
Through the practical construction of class II and class III wall rock of Qingshan Tunnel usingstep method and treatment in special sections,the relationships between design and construction of New Austrian Tunneling Method are introduced. This paper analyzes the physical parameters, determines and adjusts the support parameters through construction observation, geologic survey, rock mechanics experiments and measures on site.
