摘要
结合工程实例,分析了小相岭隧道平导喷射混凝土超耗量大的具体原因,制定了相应的措施,并在现场进行了试验段对比。试验段结果表明:成功实现了降低小相岭隧道开挖施工中喷射混凝土超耗量。
In this paper,com bined with the engineering exam ples,it analyzes specific causes of entra-large amount of concrete consumption in Xiaoxiangling tunnel flat guiding injecting process,the concrete measures are formulated and the comparison is made in the test section in the field.Experimental results show that the successful realization o f reducing the consumption o f shotcrete in the excavation of Xiaoxi&ngling tunnel.
