| Summary: |
The importance of numerical analysis in investigation of piled embankment over soft soil has been
developed since 1990. Several investigators have extended the numerical analysis to model ground
improvement using soil-column to support embankment or structures. This paper presents a numerical
analysis of the Pulverized Fuel Ash (PFA) column-treated peat and compared with field static-loading test
results. Back analysis was performed to determine the material parameters and soil stiffness surrounding
soil & soil-column. Two geometrical models were used in this analysis: (a) block (Model A), and (b)
column group (Model B). This situation was analyzed using commercially available finite element
package PLAXIS 2D ver. 8.2. It is found that both models are reliable to simulate the field static-loading
test for column-treated peat. Model B shows a higher stability to failure if compared to Model A. |
