The Metro tunnel crossing underneath highpressure liquefied natural gas (LNG) pipelines becomes common as the development of Metro and highpressure LNG pipelines. The distance requirement and settlement control standard of Metro shield tunnel crossing underneath highpressure LNG pipeline in China are not so well developed. The distance requirements and settlement control standard calculation formula of Metro shield tunnel crossing underneath highpressure LNG pipeline are summarized and analyzed by means of theoretical calculation and case studies. The study results can provide reference for determining related requirements.
