摘要
以成都地铁一号线一区间隧道穿越外环高速路的施工为例,介绍了暗挖隧道在回填土路基、高速动载和浅埋条件下进行CRD法施工技术,并对其预加固和施工不利工况作了阐述和分析,提出了相应的安全技术措施。
Based on the construction of Chengdu Metro Line 1, which goes through the outer ring highway, this paper introduces the CRD construction technology under the condition of filling soil subgrade, high - speed dynamic loading and shallow buried condition in the mined tunnel. The paper also describes and analyzes the reinforcement and the disadvantages, poining out the corresponding safety measures.
