This article gives a brief overview of the author’s and his team’s systematic research achievements in this field over the past decade - the numerical theory of structural plastic limit and stability analysis and its application in pressure vessel and pipeline safety assessment. The typical advanced numerical calculation method of the characteristics and ideas, elaborated the application of limit and stability analysis theory to solve the practical problems of the general method, ideas and processes, highlighting the typical and successful case of engineering applications, these results both theoretical innovation and development , And solved the key technical problems in the project. A relatively complete and general application theoretical system has been formed, constituting an important systematic innovation result of our country in this field. It has been approved by the Chinese National Standard (GB / T19624-2004) and the government Technical specifications adopted.
