建国三十年来,我国修建了大量隧道,积累了一定的经验。施工水平大致可分为人工为主及小型机械化两个阶段。随着铁路事业的发展,将要修建很多长大隧道,施工水平也将进入机械化施工的新阶段。为适应机械化施工,提高经济效益,本文对如何选购、使用、管理进口机械提出了意见。 Thirty years since the founding of New China, a large number of tunnels have been constructed in our country and a certain amount of experience has been accumulated. The level of construction can be roughly divided into two main stages of artificial and small mechanization. With the development of the railway industry, many large tunnels will be built and the construction level will also enter a new phase of mechanized construction. In order to adapt to mechanized construction and improve economic efficiency, this article put forward opinions on how to purchase, use and manage imported machinery.
