摘　　要：从高速公路连拱隧道的现场施工监测、支护荷载、岩土工程反分析的应用、室内试验方法的作用、数值模拟方法等5个方面介绍了高速公路连拱隧道的研究进展,指出了连拱隧道设计与施工存在的问题:连拱隧道支护强度不均匀,连拱隧道施工方法有待优化、围岩稳定性与动态施工控制有待加强,设计理论和方法不尽成熟,施工工艺繁琐、难度大,并给出了相应的解决办法。The research advance of the multi--arch tunnel are introduced in the following five aspects： site monitoring of multi--arch tunnel construction, support loads, applications of the back analysis in geotechnical engineering, role of laboratory test methods, and numerical simulation methods. This study points out some problems in the design and construction of the tunnel arch, such as uneven support intensity of multi--arch tunnel, necessity of the construction optimization, need for the strengthening of rock stability and dynamic construction control, immaturity of design theory and methods, complicated and difficult construction techniques. Corresponding solutions are provided in this paper.
