大断面、长隧洞钻爆法掘进是采用轨道式设备、抑是轮胎式设备,这对我国目前大断面、长隧洞掘进是一个值得研究的问题。在此次鲁布革水电站引水隧洞招标设计施工规划中,澳大利亚雪山工程公司咨询组,根据国外经验,对鲁布革水电站引水隧洞施工设备方案作了研究并提出轨道式设备方案。现将其主要工作成果引述如下,供参考。 Large section, long tunnel boring and blasting method is the use of rail-based equipment, is the tire-type equipment, which for our current large-scale, long tunneling is a worthy of study. In the planning of the design and construction of the diversion tunnel for the Lubuge hydropower station, the consulting group of Australia’s Snow Mountain Engineering Company made a study on the construction equipment of the diversion tunnel under the Lubuge Hydropower Station and proposed an orbital equipment program based on foreign experience. The main results of their work are quoted below for reference.
