Model tests and corresponding numerical analysis have been conducted on the isolated single stone column to study the failure behavior and bulging deformation behavior of the stone columns with
Failure of Foundation Systems Using Stone Columns AVerghese Chummar SYNOPSIS The paper presents the case history of the failure of a major foundation system
The bearing capacity of long ordinary stone columns (OSCs) with occurance of bulging failure at upper parts of the column mainly depends on confinement offered by surrounding soft soil.
Mode of Failure of a Group of Stone Columns in Soft Soil (bulginggeneral local or punching shear)identifying the mode of failure in a soil stone column
stone columns determination of the soil improvement factor bulging (Hughes and Withers)  and general shear failure (Barksdale and Bachus ) [
Stone Column Theory Applications Long stone column with firm or floating support Bulging failure Source IS (part ) the failure of stone
Failure Mechanisms of Stone Columns suggested in IS code that of Stone columns experiences less bulging leading to ultimate load bearing capacity and reduced
The failure mode observed in stone column groups was a combination of bulging and lateral deflection of stone columnsAs observed in teststhe lateral displacement of columns was mostly outward from the plate edge and was greater than that toward the plate center.
Granular columns under compressive loads experience different failure modessuch as bulging general shear failure and slidingHowever the most common failure mode for stone columns in soft clays is bulging.
Mode of Failure of a Group of Stone Columns in Soft SoilThe design procedure is presented to assist the designer in establishing themode failure of a group of stone columns (bulginggeneral
AN EXPERIMENTAL STUDY OF STONE COLUMNS IN SOFT SOILS Kausar AliResearch Scholar different modes such as bulging general shear failure and slidingFor stone
increase with the increase in diameter of stone column.When column area is loadedfailure of bulging occurs within the entire column areaThe encased stone column in layered soil also decreases with the increasing
The design of stone columns is currently based on theories developed for a single columnignoring the group interaction and therefore the group efficiencyWhereas single stone columns mainly fail by bulging a group of stone columns may fail by bulging or shear of the entire soil columns massA
A laboratory model study of the performance of vibrated stone columns bulging and columns located eccentrically under This allowed the failure patterns of the
For the stone column on the verge of bulging failurenot only lateral confining stresses but shear stresses act on its cylindrical surface A combined pile bulging failure is more likely and predicts the actual capacities of the stone columns better than two mechanism individually (Madhav and Miura ).
The bugling failure behavior involves the interaction between the stone columnthe geosynthetic encasement and the typical failure mode for stone columns has been concluded and the bulging failure mechanism of the isolated single stone column with and without geosynthetic encasement was explained in detail.
Bulging of individual stone columns Stone Columns Mode of Failure ing capacity of a stone column against bulging and general shear.
