##### 3772 Reliability Based Performance Evaluation of Stone Column Improved Soft Ground

**Authors:**
A. GuhaRay,
C. V. S. P. Kiranmayi,
S. Rudraraju

**Abstract:**

*P*) is computed for a target degree of consolidation and a target safe load by Monte Carlo Simulation (MCS). The study shows that the variation in coefficient of radial consolidation (

_{f}*c*) and cohesion of soil (

_{r}*c*) are two most important factors influencing Pf. If the coefficient of variation (COV) of

_{s}*c*

_{r}exceeds 20%,

*P*exceeds 0.001, which is unsafe following the guidelines of US Army Corps of Engineers. The bearing capacity also exceeds its safe value for COV of

_{f}*c*> 30%. It is also observed that as the spacing between the stone column increases, the probability of reaching a target degree of consolidation decreases. Accordingly, design guidelines, considering both consolidation and bearing capacity of improved ground, are proposed for different spacing and diameter of stone columns and geotechnical random variables.
