This paper mainly summarizes the structural design of mountain tunnels used to lay natural gas pipes in the 3rd pipeline project of natural gas transmission from west to east China according to the main requirement of laying gas pipes in mountain tunnels supported with concrete lining in light of geological conditions of surrounding rock, the designed parameters for tunnel lining are presented and meanwhile, the installation of gas pipe is also illustrated in the paper. The type of laying gas pipe and designing of tunnel support in mountainous regions proposed in this paper can provide practicable guidance to the design and construction of oil and gas pipe tunnels under similar circumstances.
