Sažetak
Two viaducts for a new motorway in northwestern Croatia were constructed over a very gently sloping valley. Soil investigations indicated a long landslide consisting of a medium to highly plastic clay layer slowly sliding over very gently sloping and stable marl. The foundation of each viaduct pier was designed as a parallel pair of reinforced concrete diaphragm panels extending through the sliding mass into the stable marl bedrock to resist the thrust of the sliding soil. During the construction of the viaduct foundations, several instruments were installed and readings taken on a regular basis. Almost two years after the viaduct completion, no measurable movements of foundation piers were recorded, although the slope did not yet reach its equilibrium. A three dimensional soil-structure interaction analysis was performed, using a simple elastic-plastic soil model, to verify the stability of the deep foundation. The results of the analysis generally comply with recorded measurements.
