To ensure creditability, applicability and operability of pipeline vulnerability evaluation results, a physical simulation test based on the similarity principle was carried out between landslide and pipeline to verify the deformation behavior, stress and strain distribution status of pipeline in case of landslide and to acquire the empirical formula of pipeline vulnerability and distribution of thrust applied on the pipeline by landslide.展开更多
