| Abstract | Three models of structures were studied ; the bearing element approach, the continuous slab bridge and the orthotropic bridge deck. The design proposed in this study is carried out in a rational way, in which a complete interaction among the slab, piles and the supporting soil is considered. It is proposed in this study to adopt a combination of methods in designing an approach embankment, i.e. a bridge extension for the unyielding portion, a bearing element next to the bridge extension followed by a preloaded area . From the cost analysis , it is shown that the use of bridge extension becomes more economical when the bridge approach height ranges from 2 .5 m to 4.0 m. For a level approach embankment, the length of unyielding portion needed is very short, thus a design with a bridge extension in the unyielding portion will not be much different in cost from the one with bearing element only. |
