摘　　要：双孔折板拱结构由于其自身的特点,可以极大地方便隧道现场的施工,在隧道工程中的应用越来越广泛。在施工过程中,双孔折板拱结构隧道渗水问题比较常见,直接影响隧道工程的主体结构质量和建成后的使用安全。对此,文章以乌鲁木齐绕城高速(西线)工程五一隧道工程为例,结合乌鲁木齐绕城高速(西线)工程五一隧道工程的施工实际情况,综合应用了混凝土结构自防渗技术、变形缝防渗技术和灌浆防渗技术等防渗施工技术,经实践检验,取得了良好的防渗效果,可以为类似的双孔折板拱隧道防渗施工提供参考。Due to its own characteristics,the doublehole folded plate arch structure can greatly facilitate the construction of the tunnel site,and it is more and more widely used in tunnel engineering.In the construction process,the seepage problem of the double-hole folded plate arch structure tunnel is relatively common,which directly affects the quality of the main structure of the tunnel engineering and the use safety after completion.In this regard,taking Urumqi Ring Expressway(West Line)Wuyi tunnel engineering as an example,combined with the actual construction situation of Wuyi tunnel engineering of the Urumqi Ring Expressway(West Line)engineering,the antiseepage construction technologies such as concrete structure self anti-seepage technology,deformation joint antiseepage technology and grouting anti-seepage technology are comprehensively applied.After practical testing,good anti-seepage effect has been achieved,which can provide reference for similar double-hole folded plate arch tunnel anti-seepage construction.
