Designer for caissons, along with Žeželj, was Živorad Ćertić, from Department of Geomechanics IMS. Responsibility for designing the construction belonged to Dimitrije Ćertić, from Prestressing Department of IMS, and Ilija Stojadinović from Mostogradnja, by Petrović (2005).

Fig. 8. Approximate calculation of incident load, Right Saturated soil conditions. “Prestress” soil.

Presented here is the back calculation, the vertical components of the major and minor arch, as well as the base shear at the left and right caisson locations. Assumed parameters for the replaced soil, i.e. the compacted gravel of the great arch is 40º. For the smaller arch, Fig. 8 right, the angle of internal friction is reduced to 30º, due to erosion due to flooding.
