In difficult soil conditions, engineers sometimes choose to combine reinforced soil and spread footings instead of deep foundations. Among the available techniques for soil reinforcement, vibro stone columns are frequently used to reduce the liquefaction risk, improve the soil properties and improve the overall seismic performance. While there are different models available to evaluate the bear...

This study presents the application of artificial neural network for modeling the phenolic compound migration through vertical soil column. A three layered feed forward neural network with back propagation training algorithm was developed using forty eight experimental data sets obtained from laboratory fixed bed vertical column tests. The input parameters used in the model were the influent co...

This paper discusses the ground improvement using stone columns for construction of a new lattice communication tower in gas plant Saudi Arabia's Eastern Province. The geotechnical investigation data collected at project site revealed subsurface conditions loose to very sabkha soil with low SPT and N values (< 4) between 2.7 m 13 depth. Depending on design requirements, improvements must be ...

There are a number of parameters influencing the dynamic and seismic response of bridges. Of these, two important parameters warranting special notice include: the properties of the neoperenes in the state of connection between girders and columns and the shear stiffness of underlying soil in the level of bridge substructure’s connectivity to the ground. In &#10this paper, the effects of these ...

This paper examines the possible use of a bio-cementation process to reduce excessive bulging that occurs during loading granular columns in soft clays. A 12-phase percolation bio-chemical treatment technique was used bio-cement part targeting upper section, where usually occurs. Upon application unit cell surface loads up 350 kPa, placement bio-cemented column substantially reduced vertical st...
