摘要
出碴方案是影响长距离工程隧洞掘进效率的重要因素,结合引洮二期隧洞工程地质、施工条件,分析了隧洞出碴方式的影响因素,提出了不同出碴方案,并从经济性、环保性、出碴效率等方面进行对比分析。结果:引洮二期隧洞施工推荐采用无轨方式为主、有轨方式为辅的出碴方案。
Mucking scheme is an important factor affecting the boring efficiency of long tunnel. Taking Yinzhao 2nd-stage Project with tunnel construction as example, the author analyzed the factors affecting the mucking modes combined with the geological and construction conditions; put forward several mucking schemes; and compared these schemes in respects of cost, environmental protection and mucking efficiency before the tunnel mucking scheme was recommended with trackless transport as main method and rail transport as auxiliary one.
