| Abstract | ||
| in this paper will discussed the effect of some parametric on optimum design of stone column by using ANSYS program to define the model of highway embankment with stone column and find the optimum shape, these parametric are (height of highway embankment, surcharge load (traffic load), friction angle), from first parametric it can be noted with increase the height of highway embankment the diameter of stone column increase until reach (103%)between (H=3m and H=10m), from second parametric it can be noted with increase surcharge load the diameter of stone column increase, the percentage of increase in diameter of stone column with increase surcharge load from (0 KN/m2 to 10 KN/m2) for height of highway embankment (H=3m) about (2%) but for height of highway embankment (H=10m) equal to zero, and from last parametric it can be noted with increase friction angle of stone column the diameter of stone column decrease for same height of highway embankment. The percentage of decreasing in diameter of stone column reach to (31%) if increase fraction angle of stone column from (φ=38º to φ=50º) for height of highway embankment (H=10m). | ||
