Calculation of bridge abutments is multi-faceted because there is a necessitate of analysis the structural components, which on the one hand carry all loads from the spans of the bridge into the foundation, on the other are in constant interaction with the backfill behind the main wall of abutment, which additionally also may be loaded. In the static analysis and the subsequent designing of a bridge abutment in accordance with the guidelines of the PN-EN standards some new live load models and new rules for determining the dead weight should therefore be taken into account, with respect to the principles suggested by the new geotechnical standard. This necessitates the use of multiple standards at the stage of static calculations of abutments, which can cause considerable difficulty and can extend the designing of this element. The purpose of this study is, therefore, discuss the principles determining the loads acting on the road bridge abutments, rules for determining combination for actions and the selection of appropriate partial factors for the basic ultimate limit states. Values statement of partial factors (for actions, materials and resistances) recommended by both the load standard for bridges and geotechnical standard should serve to determine of the necessary data for the dimensioning of abutments.
