Stabilnost pokosa uz prevenciju i sanaciju potencijalnih klizišta možemo smatrati kao jedne od temeljnih zadaća geotehnike. Proračun stabilnosti pokosa zahtjeva izuzetno temeljitu i detaljnu analizu jer potencijalni gubitak stabilnosti može ugroziti ljudske živote i izazvati veliku materijalnu štetu. U ovom radu opisan je problem stabilnosti pokosa riječne obale uslijed djelovanja dodatnog opterećenja uzrokovanog potresom. Proračun stabilnosti pokosa zadane obale proveden je u slučajevima kada se obala nalazi pod statičkim opterećenjem te u uvjetima kada je dodatno opterećena djelovanjem potresa. Provjera stabilnost na djelovanje potresa provedena je pseudostatičkom metodom za predviđeno potresno opterećenje te je dodatno provedena i deformacijske analize za određivanje trajnih deformacija nastalih uslijed djelovanja potresa. Prilikom provedbe analize stabilnosti obaloutvrde uočena je relacija između globalne stabilnosti i nivoa vode s kojom je obala opterećena.

Next to prevention and sanation of potential slopes slope stability can be considered as one of the fundamental tasks of geotechnics. Slope stability calculation requires extremely thorough and detailed analysis because the potential stability loss can endanger human lives and cause immense material damage. This paper describes the problem of slope stability of a riverbank due to additional load caused by an earthquake. The slope stability calculation of the given riverbank was made for the case in which the riverbank stays under the static load and for the case when it stays under additional load due to earthquake effects. The analysis of resistance on earthquake effects was performed by means of pseudostatic method for anticipated earthquake load. Additionally, the deformation analysis for the measurement of permanent deformations caused by earthquake effects was performed, too. While doing the revetment stability analysis it has been observed that there is a correlation between global stability and the water level of the water which loads the riverbank.
