This paper introduces the assumptions, procedure and results of a number of three dimensional numerical analyses for simulating the behavior of an encased, versus unencased, stone column group installed in a very soft soil layer; the finite element technique ...

<p>In this study, application of modified dry bottom feed stone column as one of the dominant ground improvement methods in the region was introduced. Also, a numerical analysis is carried out to check its performance with respect to displacements. According ...

<p>Ground Improvement techniques are often used to improve sub soil properties in terms of their bearing capacity, shear strength, settlement characteristics, drainage, etc. These techniques have a wide range of applicability from coarse grained soils to ...

<p>The ground improvement performed at the site of two 190-ft (57.9 m) diameter, 40-ft (12.2 m) high, 8 million-gallon (30,300 m3), circular steel water storage tanks consisted of installation of stone columns to mitigate liquefaction and lateral spreading ...
