【摘要】 在钻爆法开挖大型地下洞室的过程中,施工机械的配置情况在一定程度上决定了地下洞室的施工程序和开挖方法。结合若干地下洞室开挖实例,分析了施工机械对地下洞室开挖方法的影响,结果表明:施工机械对总体施工方案的影响是显著的,施工机械的性能直接影响了开挖程序的制定,而各种配套施工机械对工作净空的要求也是不可忽略的因素。更多还原

【Abstract】 During the excavation of large underground tunnels,the construction equipment dominant the construction procedure and excavation methods.According to several examples of underground tunnel excavation,the influences of construction machinery on the tunnel excavation method are analyzed.It shows that the equipment has a significant influence on the general construction scheme.The excavation procedure is directly affected by the performances of construction machineries.And it can’t be ignored that different construction machineries have different requirements for the working headroom.更多还原
