construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to  reduction of embankment slope gradient, which significantly increases the volume of soil operation. generally, micropile as a reinforcing element with t...

in the first impounding of rockfill dams, additional settlements occur in upstream side in saturated rockfills due to collapse phenomenon even high rainy seasons can cause additional deformation in the dumped rockfills. unfortunately these displacements are not taken into account in the conventional numerical models which are currently used to predict embankment dam behavior during impounding. ...

it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...

the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...

The reduction of train-induced ground vibrations by different railway lines and mitigation measures in the propagation path is analysed a unified approach two-dimensional finite element calculations where expressed as amplitude ratio between specific reference situation (the surface track without measure). In general, there no at low frequencies, becomes stronger with increasing frequency. A ma...

The stability of the embankment’s slopes is a critical aspect geotechnical engineering and it essential to guarantee effectiveness factor safety prevent any potential failures in slope both during post-construction. current study consists two parts; first part behavior geogrid-encased granular columns their interaction with soil at shear surface generated by slippage soil, while second changing...
