خلاصه مقاله:

soils using ANSYS 10 finite element software. First, a sandy soil media with properly given properties is modeled and under increasing loading its bearing capacity is studied. Then micropiles with 20cm diameter and 4m length, with various inclinations 0 to 45 degree with the vertical axes which are used in practical usages inserted in this sandy soil, and bearing capacity of soil is studied. Next the bearing capacity graphs for this sandy soil with and without use of micropiles with various inclinations are plotted and effects of them are studied. Finally comparisons between results obtained from these studies are done. The obtained results show that use of micropiles in sandy soils leads to increase in bearing capacity up to 110 percent. The results of this study can provide valuable information about use of micropiles in sandy soils.
