Abstract: During many earthquakes, soil liquefaction causes dramatic damage. The use of a granular column is a ground-improvement technique used to mitigate soil liquefaction. The present paper studies the performance of reinforcement ...

Abstract: An analytical model dealing with the problem of an expanded cylindrical cavity in an elastoplastic medium is presented. The constitutive material is assumed to be weightless, homogeneous, and isotropic; its resistance is ...

Abstract: The design of foundations on soft ground reinforced by columns usually involves two important verifications, namely, checking for adequate bearing capacity and checking for acceptable settlement performance. This paper ...

Abstract: The ultimate bearing capacity of a strip footing on soil reinforced by a trench has been studied in the framework of limit analysis. Existing contributions were reviewed and were compared with numerical results predicted ...

Abstract: This study applies the limit analysis to estimate the bearing capacity of a rigid foundation on a soil reinforced by a group of floating columns. The lower bounds of the bearing capacity are derived in terms of a dimensionless ...

Abstract: During many earthquakes, soil liquefaction causes dramatic damage. The use of a granular column is a ground-improvement technique used to mitigate soil liquefaction. The present paper studies the performance of reinforcement ...

Abstract: This paper studies the effect of certain parameters closely related to the design of column foundations such as the improvement area ratio, especially at low values, e.g., 1 and 4%, and the grain size of the column material ...

Abstract: This paper studies the design of foundations built on thick compressible soft soil layers that are reinforced by floating columns. Based on a recent methodology, the suggested design combines the bearing capacity and ...
