000004530 520__ $$2eng$$aThe paper deals two problems of a theory of the Code. Interaction between a handmade structure and touching soil/rock mass or behaviour of a solitary soil/rock mass are extraordinarily complex tasks of mechanics of which objects distinguish themselves by very complicated non-linear behaviour. Generally in mechanics, it is well-known that an application of coefficients and factors for non-linear or the 2<sup>nd</sup> order analyses is incorrect. Also, a principle of superposition is inapplicable for these analyses. What it is very strange it is that an ordinary official geotechnical practice in Europe (EC 7-1) does not respect this basic principle of mechanics applying a statistical definition of characteristic value and material partial factors(probably B. Hansen 1953). The application of any changes of real physical mass properties for inputs of the Ultimate Limit State Design of EC 7-1 appears to be a rejection of the principle of mechanics. Further, a code theory of earth pressure appears also to be disadvantage, not very precise and involving risks for designers (see Fig.2 and compare both diagrams). The paper presents concepts of possible solutions of the problems. 
 The Code development has continued too long time (about from 70ties). It has been done a lot of good work through the time and the Code is the very great work. However, if the code shall be a great good work its theoretical base has to be advanced. This should be considered to be a foremost task of the Code calibration. (References see in the paper.)
