This research discusses the use of stone columns in increasing value safety factor on soils that have potential to experience liquefaction. study aims determine sandy soil area and after Stone Column planning. The method used liquefaction is Seed et al, based interpretation SPT (Standard Penetration Test) data using column as a improvement method. Based results study, it known each point has ex...

Stone column replacement of soft soil foundation construction method is more and used in water conservancy projects. On the one hand, stone has high permeability, which enhances dissipation capacity excess pore pressure; on other it a stiffness, reduces additional stress soil, therefore pressure. These two mechanisms work together to improve bearing soil. In previous plane strain transformation...

BACKGROUND AND PURPOSE The present study was carried out to compare the efficacy of ESWL treating radiolucent ureteric calculi visible in the ureter after application of contrast media. MATERIAL AND METHODS Medical records of 47 patients who had verified ureteric calculi by intravenous urography and retrograde pyelography were included in this study. Patients had undergone ESWL treatment afte...

Stone columns are a more economical and efficient method to enhance the strength of expansive soils. Using granular blanket over top ordinary stone (OSC) improves drainage distribution applied stress impending from superstructure. The present study studied effect geogrid layers in (GB) OSC numerically using 'PLAXIS 2D'. 'Mohr-Coulomb failure criterion was deliberated for column, blanket, soil, ...
