Soft soil has a small shear strength, large compressibility, and also coefficient of permeability. So that soft can be used as the basis construction, improvement measures are needed. One method is stone column. in this research, parametric study effect column on bearing capacity was carried out. Parameters were varied diameter, distance angle configuration pattern. Variations diameter 1 m, 1.2...

Potamotrygon limai, sp. nov., is described from the Jamari River, upper Madeira River system (Amazon basin), state of Rondônia, Brazil. This new species differs from congeners by presenting unique polygonal or concentric patterns formed by small whitish spots better defined over the posterior disc and tail-base regions. Potamotrygon limai, sp. nov., can be further distinguished from congeners i...

Stone columns are being used to reduce soft soil settlement and increase load-carrying capacity. Since there is inadequate lateral support from the local native soil, undergoes excessive under vertical loading. This issue effectively resolved by suitably encasing stone column material geosynthetic with significant axial stiffness, which provides required additional confinement reported in liter...

Liquefaction is a disaster that can damage building infrastructure. This all too common in granular sandy soils. due to the subsidence and instability of soil when subjected shocks such as earthquakes. For this reason, mitigation efforts are needed reduce risk liquefaction. study will compare effectiveness influence micro-pile, stone column, densification methods on soils at Central Java PLTU s...
