The XinYueZhe pipeline is the longest coal-to-gas pipeline to be constructed in China. The strain-based design method will be applied in the pipeline through active fault. In this article, the design criteria, check standard and applied range of strain-based design method were introduced. The numerical model of pipeline through active fault was set up based on the nonlinear finite element method. This model adopted pipe shell coupling method, which ensures the calculation accuracy and also with good efficiency. Combined with the strain-based design flow, the design process of the pipeline crossing the active area of fault instance was given, which provides reference for design and construction of pipeline through area of fault.
