Szukana fraza: [Abstrakt = "The road viaducts which span over Wał Miedzeszyński Street and are part of Siekierkowska Route form an element of Warsaw’s road infrastructure which was constructed in the years 2000÷2002. They are triple\-bay, reinforced concrete facilities whose end sections are supported on embankments made of reinforced soil. In July 2016 a fault with a height of 15\-25 mm was identified in the support P1, in the expansion joints. The fault caused heavy \(discernible\) vibration as trucks passed over the viaduct. While accounting for the observations, surveying measurements and vibration measurements as well as the available geotechnical surveys, the paper presents the results of the analyses which are aimed at explaining the origin of the fault. Two potential scenarios of occurrence of additional settlements have been adopted and discussed as the major reasons causing the fault. The first one concerns settlement of the supports as a result of condensing of the alluvial sands, caused by the dynamic influence of the loads\/forces affecting the road surface of ul. Wał Miedzeszyński. The second one is the delayed consolidation settlement of the cohesive soil layer in the substrate of the embankment made of reinforced soil, which could have led to raising of the ends of the transition slabs above the road surface on the viaduct. Analytical and numeric approaches were used during the analyses while relying on PLAXIS \(2D\) and MIDAS \(3D\) software. A proposal of elimination of the fault is also presented."]
