Abstract_English:\rLateral global buckling plays an important role in the design and integrity assessment of HP/HT submarine pipelines. With the development of deep-sea oil and gas resources,a considerable amount of research on the global buckling of submarine pipelines has been conducted in the past 40 years,resulting in substantial progress been made in the field. This paper describes the history and major research achievements of lateral buckling studies on submarine pipelines. It covers the theoretical analysis of lateral buckling,experimental study on pipe-soil nteractions and thermal buckling response of pipelines,and finite element analysis(FEA) of global buckling. This paper also highlights the design of buckling mitigation measures for the pipelines,and finally identifies the areas for further development.\r
