This study aims to address the challenges to allow fire protection pipelines passing through geological defects ( ground fissures ) in Xi’an metro area. The analysis of the relevant domestic technologies in passing areas with settlement joints is conducted. To calculate the proper expansion/contraction length of the water pipelines passing ground fissures and the mechanical strength of pipeline, the movement and settlement of local ground fissures are taken into account. The pipeline accessories and installation details are then determined to ensure the security and reliability of the fire protection pipeline.
