重庆轨道交通10号线穿越深回填区隧道结构方案研究

城市轨道交通建设中,区间隧道结构不可避免地要穿越深回填区,合理的隧道结构方案对施工安全和轨道交通正常运营至关重要。文章对重庆轨道交通10号线穿越深回填区的各种隧道结构方案和相应处理措施进行综合分析,比选各方案的优缺点及适应性,最后选取马蹄形断面+微型桩基暗挖方案作为重庆轨道交通10号线穿越深回填区方案。

Study on Tunnel Structure through Deep Backifll Area on Chongqing Line 10

In urban rail transit construction, tunnel construction will inevitably pass through deep backfill area and reasonable tunnel structure is essential for construction safety and normal operation. The paper makes comprehensive analysis on a variety of tunnel structural schemes and corresponding control measures on Chongqing line 10 passing through deep backifll area, a comparison of the advantages and disadvantages and adaptability. The final selection is the scheme of horseshoe section＋micro pile underground excavation as the scheme of Chongqing line 10 passing through deep backifll area.
