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...

Deep mixing columns commonly are used to reduce settlement under road and railway embankments on soft soils. However, the structural behavior of soil volume improved with is difficult predict, due existence considerable uncertainties in process interaction between untreated soil. This paper probabilistically investigated two serviceability limit states deep from a system reliability perspective...
