Buried pipelines are a practical and cost-effective way to transfer liquids and gases including clean water, sewage, oil, and natural gas. However, pipelines are frequently subjected to numerous geohazards, such as differential ground movements caused by earthquakes, landslides, fault movements, and other causes. It is vital to examine the performance of the pipes exposed to the threats to ensure pipeline safety. The applicant's study focuses on evaluating the performance of underground pipelines exposed to geohazards using experimental and computational approaches in order to establish a pipe design method. Large-scale static experiments are used to observe the pipe and soil reactions during ground movements, and finite element models are employed to forecast behavioral patterns.
The expertise on earthquake-induced consequences on pipelines is weak in Canada. The proposed project would use the partners' experience to supplement the applicant's competence and boost his research program in Canada. The applicant and the collaborators will exchange their experience, knowledge, and ideas in the proposed joint project and create a new worldwide research relationship. A thorough strategy will be first established to carry out an experimental and numerical investigation of buried pipelines using the resources of the collaborators.
