The surrounding environment of tunnel is complex.The space of tunnel and pipeline is only 0.8 m. According to the construction schedule requirements, the upper release line should be constructed first, and the main track constructed latter.In order to ensure the safety of pipelines and tunnels, using the finite element software to simulate the effect of the treatment analysis, and the program, numerical analysis, construction technology, ground reinforcement, support of the cave and other aspects were selected from. At last, the interval through high pressure gas pipe mining methods are deep grouting in roof, center drift method in step and the program grouting the floor of release line. From the final monitoring data show that the chosen project design is reasonable construction measures, economic. Tunnel and pipeline deformation does not exceed safety requirements. This conclusions have reference and guiding significance for the design and construction of similar city subway projects.
