Buried pipelines in sloping ground and potential buckling during operation

石油和天然气管道通常穿越各种地面条件，从相对平坦的地区到斜坡，如穿越丘陵、山脊和河流。地面变形/边坡破坏和运行过程中的隆起屈曲对管道的结构完整性、安全性和可操作性构成重大威胁。加拿大拥有一个由大约115 000公里的地下能源输送管道组成的网络，每天都在运行，输送石油和天然气。目前的指南建议使用简化的方法，这有一些局限性。在拟议的项目中，将进行数值分析和实验室测试，以更好地了解这些复杂的机制，以开发更好的方法来评估管道在倾斜地面中的响应，并可能经历屈曲。两个博士和一个硕士的候选人将通过这项研究补助金的支持。利益相关者将寻求研究成果，包括工程服务公司，运营商，石油和天然气公司，监管机构和学术界，以解决限制因素（例如技术，经济或物流）并满足可接受的风险和安全目标（例如社会，环境）。

Oil and gas pipelines generally traverse over a large distance through various ground conditions, from relatively flat areas to sloping grounds such as crossing hills, mountain ridges and rivers. Ground deformation/slope failure and upheaval buckling during operation pose a major threat to the structural integrity, safety and operability of the pipelines. Canada has a network of approximately 115,000 km of underground energy transmission pipelines that operates every day to transport oil and natural gas. The current guidelines recommend using simplified approaches, which have some limitations. In the proposed project, numerical analysis and laboratory tests will be performed for a better understanding of these complex mechanisms to develop improved methods for assessing the response of pipelines in the sloping ground and that might experience buckling. Two PhD and one Master's candidates will be supported through this research grant. The outcomes of the research will be sought by stakeholders including engineering service companies, operators, oil and gas companies, regulatory agencies and academia to address constraints (e.g. technical, economical or logistical) and satisfy accepted risk and safety targets (e.g. societal, environmental).
