Abstract Tunnels are taking a bigger percentage of the total length of roads and railways built in China because a sophisticated environmental protection system is being established up gradually. Compared with big-span tunnels，multiple-arch tunnels are safer，more beautiful in structure and easier in construction. Compared with building separate tunnels under the same geological condition，multiple-arch tunnels cover less area and need less investment. Restricted by the traditional construction method，most multiple-arch tunnels are short. Combining the experience of building multiple-arch tunnel，the construction of the multiple-arch tunnel and the control and prevention of the fault common in building multiple-arch tunnels are described.

Key words： tunneling engineering multiple-arch tunnel construction technology quality control
