摘要
随着科学技术的进步和生产管理水平的不断提高,我国修筑长大软弱围岩隧道的能力不断提高。该文以神(木)至延(安)铁路W9标隧道施工为例,阐述了软弱地质围岩地段隧道的施工方法、技术要领。文章强调地质预测和地质灾害预报的重要性,总结成功的做法,为同等条件下的施工提供借鉴。
With the progress of the science and technology and the continuous enhancement of the production management level, the ability to construct the long and large weak country rock tunnel is continuously enhanced in China. Taking the construction of Shenmu to Xi’an Railway W9 Bid Tunnel as an example, the article sets forth the construction methods and technical gist of the tunnel in the weak geological country rock area. The article emphasizes the significance of geological forecast and geological disaster forecast, and summarizes the successful procedure, which can be referred for the constructions under the same condition.
