Experimental investigation of soil - structure interaction for transition slabs of integral bridges

Résumé

This paper presents the results of an experimental test series on the soil-structure-pavement interaction in the vicinity of the transition slab at the end of an integral bridge. The main function of transition slabs is to ease the transition between the bridge deck and the embankment in case of differential settlements. Additionally, in the case of integral bridges, they can solve the problem of moderate imposed longitudinal deformations at the bridge ends. In this case, the displacements imposed to the transition slab can lead to vertical and longitudinal surface displacements and to cracking of the pavement. Based on the observed behaviour, some recommendations are proposed for the geometry and surface conditions to optimise the behaviour of the transition slabs.

vignette|Pont permettant le passage de la ligne C du métro de Rotterdam, à Capelle-sur-l'Yssel (Pays-Bas). vignette|Pont sur la rivière Moyka à Saint-Pétersbourg, Russie Un pont est un ouvrage d'art qui permet de franchir un obstacle naturel ou artificiel (dépression, cours d'eau, voie de communication, vallée, ravin, canyon) en passant par-dessus. Le franchissement supporte le passage d'humains et de véhicules dans le cas d'un pont routier, ou d'eau dans le cas d'un aqueduc.
Tablier (pont)
A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel, open grating, or wood. Sometimes the deck is covered by a railroad bed and track, asphalt concrete, or other form of pavement for ease of vehicle crossing. A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system.
