NUMERICAL STUDY ON THE BEHAVIOR OF INCLINED MICROPILE
Using results from 120 numerical modelings for micropileswith :
• D = 100 , 150 , 200 & 250 mm
•
L = 4 , 5 , 6, 7 , 8 , 9 , 10 & 11 m• M/F = 1 , 2 & 3
The following multivariable interpolation
polynomial was employed:
U = Lateral Displacement (mm)
F = Applied Lateral Load (ton)
M = Applied Bending Moment (ton.m)
D = Micropile’s Diameter (mm)
L = Micropile’s Length (m)
A relationship was developed from statistical regression analysis
of thefiniteelement modelingcomputationstoestimatethelateraldisplacement of micropiles inclined at an angle of 30o in silty
sands.
This paper presented three-dimensional finite element analyses
of single micropile subjected to simultaneous lateral load and
bendingmoment usingABAQUScode.
The effect of micropile’s geometrical parameters ( diameter,
length and inclination angle ) on soil-micropile systemresponse
were investigated.
