Small scale modelling of brickwork arch bridges using a centrifuge

The development of a small - scale geotechnical teaching centrifuge

Geotechnical engineering is a core discipline within civil engineering that supports the infrastructure development which underpins modern society. The simulation of realistic geotechnical design at undergraduate level is often restricted to routine calculation-based methods reinforced by simple element laboratory tests which fail to provide a holistic learning experience. Using the latest rese...

Failure Modes Analysis of Stone Arch Bridges

A destruction test based on the bridge safety appraisal is one way to verify the failure law of an actual bridge. In this paper, a stone arch bridge in a 1:10 scale model and with a span of 60 m (namely, an arch bar of the same length as the object of test) has been tested, methods of its whole test and loading process introduced, and ultimate bearing capacity, deflection and development rules ...

Hydraulics of River Flow Under Arch Bridges

IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera­ tion, often necessary, is the length of the bridge. In certain circum­ stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...

Treatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system

The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...
