Earth pressure is a load and the theory solves a contact task on structure rear face between structure and soil mass. Owing to very complex behaviour of soils (three-phase substance) a theoretical problem is very complexly non-linear. From European point of theoretical view precariousness and hazard of design analyses is caused by two interacting problems in two used theories: design theory (Limit State Design) and an inaccuracy of lateral earth pressure theory itself. The paper presents new results of earth pressure analyses according to both EUROCODE 7-1 (Annex C) on a database of soil properties ITAM 2012 and a classical formulas based. Further, selected results of long-term basic research are given to show hazard of the theory incorrectness. Some recommendations for practice are given.
