Numerical Analysis of Failure Mode of Micropile in Cohesive Soil

Abstract

In this paper, fnite element was used to study the behavior of micropile. The model was developed using PLAXIS 3D foundation program. Micropiles are tested by the static axial load testing of individual piles. In the FE-analysis the pile is assumed to be linear elastic and for the subsoil is assumed as Mohr-Coulomb model. The model was developed to simulate the micropiles type A where the grouting is applied by gravity. This modeliscompared with the results of the pile load test. A good agreement was obtained with the experimental results. Finally the failure pattern was investigated.
