... it was built in the dry then a new man made channel was cut under it to eliminate a sharp S bend in the Yarra River. The south abutment of the bridge is founded in weak siltstone, while the north is founded in soft alluvial deposits. The bridge consists of 3 arches. The northern most arch has exhibited some...

.... Thus, dams were occasionally built on landslides without a complete understanding of the problems involved. Today, however, every effort is made in the selection of dam sites to use foundations and abutments that are generally impervious and capable of withstanding the stresses imposed by the proposed...

... ABSTRACT: The test construction was performed with large-scale models of embankment and abutment to investigate the behavior of the abutment built on soft ground and the stress in the foundation. Two kinds of abutment, named Type-A without pre-load and Type-B with pre-load, were used...

... and extreme strain at the abutments and midspan, the midspan deflection, and the shape of the thrust line. Finally, these values are correlated to the analytical ones which correspond to the simpler voussoir beam idealizations. INTRODUCTION The behaviour of an underground roof composed of stratified...

... increase in the traffic density and to the corresponding increased use of heavy vehicles. The strong tectonic activity in the greater foundation area of the abutments, combined with the high seismic activity, were the major serious problems for the design of the project. For this reason, extended...
