Limit displacement of a landslide for an X80 buried pipeline crossing it
Zhongguo dizhi zaihai yu fangzhi xuebao, 2023 When transporting natural gas, long-distance pipelines will inevitably pass through areas with frequent geological disasters, and landslides are the most threatening to pipelines. Therefore, it is very important to study the safety assessment of pipelines under the action of landslides.
