The article deals with the development of a new combined calculation method "Large Block Combined Method" in the mechanics of solid deformable seals. In the present work, the author's opinions on the urgency, purpose, research subject and other issues of the development of this method are discussed. This method will be mainly used to study the tense-deformed condition of objects with very complex structures. It relies on the applications of the finite element numerical method and the large block analytical method. Such a method will be effective in cases where part of the object to be examined can be considered as elements with simple and complex structure, where the analytical method of large blocks will be used, and the rest as a space with very complex structure, where the numerical method of finite elements will be used. In addition, the contact conditions required to ensure the simultaneous operation of these parts of the object under consideration must be met. The article discusses the issues that favor the combined method of large blocks over the finite element method and the analytical method for large blocks. Especially noteworthy is the issue of specifying the results of the tense-deformed state of objects with complex structures using a new calculation method.
