In 1891 a report was published by an ASCE committee to investigate the cause of the Johnstown flood of 1889. They concluded that changes made to the dam by the South Fork Fishing and Hunting Club did not cause the disaster because the embankment would have been overflowed and breached if the changes were not made. We dispute that conclusion based on hydraulic analyses of the dam as originally b...
Stepped block protection has considerable potential as a low-cost method for the construction of chute spillways and the protection of embankments from erosion by overtopping flow. Stepped spillways are structurally stable, resistant to water loads and significantly increase the rate of energy dissipation on the spillway face thus eliminating or greatly reducing the need for a large energy diss...
Compost use in landscaping and erosion control applications has become widespread. Various types of composts have been utilized on highway embankments for soil conservation and runoff reduction. Different compost materials could have different erosion control effects. The objective of this study is to investigate the erosion resistance of three commonly used composts and their effects on slope ...
Australia’s first trains designed 200 km/h are being delivered to Western Australia for the TransWA country rail system (Hammond, 2003). The construction of a railroad structure in soft clays in itself is a significant cost, and many design problems are caused by the requirements that the railroad embankment be visible and noise controlled. In this paper case histories of the use of ground impr...
In this work, the settlement deformation of soft-soil subgrade and law geogrid were studied based on field tests carried out pile-supported reinforced embankment Rongwu Expressway in Xiong’an New Area. The reinforcement area underlying layer embankment, transverse longitudinal sections subgrade, bidirectional analyzed. results show that reducing pile spacing height can effectively reduce founda...
This paper investigates the effect of different geometries approach embankments and guides banks on flow pattern bed shear stress values in skewed bridges compound channel using three-dimensional numerical modelling. First, model was evaluated based results existing laboratory studies. After ensuring its proper performance, elliptical guide bank three types abutments: vertical-wall, spill-throu...
The observation of failure surfaces within column supported embankments is critical to understanding how the embankment stresses are transferred towards heads. In this study, finite element simulations utilising a strain softening constitutive model, non-local regularisation and Arbitrary Lagrangian-Eulerian formulation used examine these over various geometries. This methodology offers insight...
