Abstract：
Based on the construction for pipeline suspended in a subway station, set down two scenario to suspend pipeline by use steel girder or military trusses; according to the result of numerical simulation for the two scenario, used steel girder can not satisfy the need of security, it should choose the military trusses to suspend pipeline in the construction process; introduced the construction techniques and monitoring of pipeline suspended in the construction process, the result of monitoring indicated that use the military trusses to suspend pipeline is scientific and fit.
