General, the use of micropiles for slope stabilization features several strengths, such as their capability to be put in in confined spaces, their capability to be set up in a variety of soil conditions, as well as their capability to supply a large degree of stabilization with small disturbance into the bordering region.
The design will have to also bear in mind the probable for seismic activity, which often can raise the danger of landslides and slope failures.
With this potential, the sheet piling functions being a beam less than load. Therefore, it will have to resist bending. In certain apps, the opportunity to resist bending will not be as vital because the energy with the interlock.

In this particular software, the soil gets part of the pile and is carried down with it. This core of compacted soil will help to compress the bordering soil, allowing it to build resistance to additional displacement.
