4. Static Behaviour Of Micropiles Foundation (With Different Inclination Angles) On Slopes

Recently, the use of micro-piles has widespread since it ensures a support system with minimal soil movement and less damage to neighboring buildings.  Micropiles could be applied in different types of soils, individually or as a group, vertically or with different angles of inclination. Therefore, this research has created a physical model in the laboratory to study the behavior of micropiles with different angles of inclination. Studying the static bearing capacity of Micropiles group, comparing the load-settlement curves for the many cases, comparing the forms of failure that occurred and then determining the optimal placement of the micropiles which gives higher strength values compared to the vertical ones. The experimental and analytical methodology was followed in completing the research. The research concluded that Micropiles give an increase in the bearing capacity from 1.7 to 4 times depending on the angle of inclination of the micropile and the ratio of settlement. Also, the inclination of the micropiles gives a noticeable increase in the bearing capacity, however with the increase in the ratio of settlement. At a settlement ratio ranges between of 10% and 20% of the foundation width, the negative angles show better results than positive angles in terms of bearing capacity. At high settlement ratios range from 30% to 40%, positive angles are preferred
