Based on sealed pipe tee on-site construction mechanical properties calculation, in combi- nation with the test pressure of the plugging process and contact problems, the calculation results of data was analyze in order to establish the optimization function, carry out multi-design variables optimization to achieve optimal design of the existing structure, and thus automatically re-generate optimization model, and complete the mechanical properties calculation and the strength analysis of the optimization model. The research results show that the optimized solution not only saves raw materials,also cuts maximum stress down by 29%. At the same time,the methods and results of the study can be used for the evaluation and optimization of the safety of the pipeline construc- tion, and have guiding significance on site production.
